FC6 boots up to a blank screen

[turquoise70]

Hi everyone,
I'm the newest of possible types of newbies with Linux; I just started trying to use it for the first time tonight. I'm having some trouble. The bottom line is, I'm absolutely Linux-illiterate at this point.

I've got an AMD 64x2, Windows XP (so I'm trying to dual boot with FC6 on another partition of the same HDD), ATI Radeon x1600 graphics card, 512 mb of RAM

I downloaded and burned all 6 FC6 CD files to CDs (64 version), and installed FC6. This seemed to go smoothly-- although at one point when it was doing something with the video, the screen displayed a very garbled version of my motherboard's bootup image, tiled.

The problem began when installation stated that it was complete, and (presumably) went to start up FC6. However, when it did this, the screen went blank-- in fact, my monitor read "entering power save mode" like it does when the computer shuts off. The computer is still running, but the monitor I guess isn't recieving any video signals. The system responds to some things apparently-- I can still turn the Num/Caps/Scoll Lock on and off and the LEDs respond.

So my computer is set up to dual boot, and FC6 is set up as the default, but it arrives at the blank screen every time it goes to start up what I'm presuming is the graphical part of the OS.

I know I'm probably leaving out some crucial information, but like I said I'm very new to this. Anyone think they can help me given what we all know now?

Thanks in advance peoples, I appreciate any help

[glennzo]

We can help you. In my opinion this is a common problem. But a few questions first. Are you using GRUB to handle booting? Do you know your monitor's horizontal and vertical refresh rates?
The problem is likely a mis-configured /etc/X11/xorg.conf file. If we make a few small changes to it we can probably get you up and running in no time. It's usually pretty simple.

[el_diablo4303]

i do have same problem with turquoise70. some told me that to add something like this....

->When grub appears hit the enter key and type e [for edit]
and add the following to your kernel boot line.
mode=vesa resolution=800x600

It should look like this

.........rhgb quiet mode=vesa resolution=800x600

If this allows you to boot properly then you can system-config-display and sort out your hardware
configuration <-

sadly..it doesnt work for me. i'm using gigabyte 945P-S3 motherboard...SATA...ATI Radeon X1600PRO PCI-E.

[glennzo]

When grub appears, scroll to the OS you want to boot and press 'e'. Then arrow down to the second line, the one that looks similar to this: kernel /boot/vmlinuz-2.6.18-1.2869.fc6 ro root=LABEL=/ vga=791 and press 'e'. Now you can edit the line. The sample line I used is from my own grub menu. Using that as an example, get rid of 'vga=791' and replace it with '3'. Press 'enter' and press 'b'. This will accept the change and boot Linux to level 3 where you can then log in as root and edit your /etc/X11/xorg.conf. Change to your /etc/X11 folder. Using an editor, open xorg.conf. Look for the text below in your file.

SubSection "Display"
Depth 16
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 24
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection

Remove "1280x1024" from both lines. Save the file. Now you should be back at the command prompt. Type 'startx' and press enter. If all went well you should get into the graphical desktop. If it worked, I'd reboot and log in as your regular user. You don't want to be working as root. If not, we go back a step. Keep us posted if you will.

[turquoise70]

Yes, I'm using GRUB to handle it. And I changed the last bit to 3, and have proceded onwards. Yay! No more black screen.

So now I'm looking at a command line and i've logged in as root with the password I set at installation. But...I don't know how to change to that folder, or open that file.

I tried just typing in /etc/X11/xorg.conf but it said permission denied.

Update: I figured out how to change to the /etc/X11/ directory and I can see xorg.conf in the list of files, but I don't know how to edit xorg.conf.

[glennzo]

As root, type cp xorg.conf xorg.conf.bk which will backup the untouched xorg.conf file. Then type vi xorg.conf. As soon as vi opens, hit the esc key and then the insert key. That puts you in edit mode. Move down until you see the lines I talked about, make your changes, hit esc then, in this order, :wq! ,that's a colon the letter w the letter q and the exclamation point and press enter. That will save the file and exit the vi editor.

[turquoise70]

Okay. I've gotten as far as opening xorg.conf and entering edit mode, but no such lines exist in the file.

at that part in the file, it instead reads:

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection

There doesn't appear to be anything about screen resolutions. What should I do from here?

[glennzo]

Here's a clip from xorg.conf from one of my Linux installations.
Subsection "Display"
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
Try adding the Modes line just as you see it here to your file, save and type startx. Keep us posted. We'll get it working for you.

glennzo....
this is my kernel that u had said go to second line....grub edit>kernel /vmlinuz-2.6.18-1.2798.fc6 ro root=/dev/VolGroup00/LogVol00 rhgb quit ... i add 3 at the back..then move on to root... then i log in as root and the password.
problem here...i don't know how to change to that folder, or open that file.

i had try typing -> /etc/X11/xorg.conf but it said permission denied.

i got stuck here.... could u point me to something?

[sdowney717]

Here is my xorg.conf as found in /etc/X11

Please help me a little here as well. Sometimes when I boot, the X server gives me a blank screen past UDF line as it is booting. The only way I can get it to work if this happens is to boot into win XP, shut down and reboot fedorca core 6

here is my grub

Type, in this order"
su (press enter)
(enter root's password) <--don't type this :D
cd /etc/X11 (press enter)

You are now in the /etc/X11 folder

Type
cp xorg.conf xorg.conf.bk <--This will make a backup of the file for use later :D
vi xorg.conf

Make the needed changes. Save and exit vi by pressing the escape key, the colon key and wq! and press enter.

Type startx at the prompt. Feel the magic. Don't give up if there's no magic.

[turquoise70]

Excellent! Absolutely excellent, thanks so much glennzo :D
my .conf file is fixed and FC is working like a charm, and it looks lovely by the way. Now to get the internet configured...

[el_diablo4303]

thnaks glennzo. i've done it. now i can enter graphical interface. i had try to change monitor property..but i reboot it...same problem appears. i've check the xorg.conf file. there some changing in it. new line were added for monitor if i'm not mistaken.
then edit back...save it..follow ur instruction again with typing startx. now some errors appear.
Error message like this :

then i reinstalled fedora..repeat back then steps to edit the xorg.conf. i've tried Modes "1024x768" "800x600" "640x480" but it doesn't work. then i delete "1024x768"..its work. however the resolution only "800x600" and "640x480". now i can use fedora with no problem like before.
now what should i do? i've graphic card but no onboard vga. the resolution is rather small with big icons for me. how can i install the graphic card driver or else to get better resolution?

Change the horizontal and vertical sync ranges, where I've made the text red. It needs to read HorizSync 30 - 95 VertRefresh 50 - 160. Save and exit the editor. Type 'startx'. Once you get a screen, log out and log in as your regular user and type 'startx'. Better off to just reboot and log in as regular user.

I'm losing track of where you are at. Did you change your horizontal and vertical refresh rates to HorizSync 30 -95 and VertRefresh 50 - 160 ? Do that and if it works go back in and add the "1024x768". Most monitors can do that resolution no problem.

[el_diablo4303]

i've just done that. thankfully..its work.
now...should or shouldn't i install driver for my graphic card n motherboard? if should...then how m i going to install those drivers?

[glennzo]

I have an NVidia GeForce FX 5200 128MB/AGP card. I've had my Fedora system running with both the 'nv' (default) driver and the 'nvidia' driver. The system works fine with both drivers. I think that the main advantages of having the correct driver for your video card are that you can get the resolution that you want instead of just any resolution that works and, in my case, I'm running Beryl, which supplies awesome special screen effects. I don't think I could do that with the default 'nv' driver. If you're just using the box as a 'nothing special' workstation I'd stay with whatever works. If you want to try the 'correct' driver, by all means, go ahead, but backup your xorg.conf first. That way, if something bad happens you can always restore the old xorg.conf and be up and running in no time.

[el_diablo4303]

i'm using ATI RADEON X1600PRO. i'd surf the net..then i found this url http://ati.amd.com/support/drivers/linux/linux-radeon.html. on this page it said something about this :

ATI Driver Installer - Automated installer and Display Drivers for XFree86 4.3 and X.Org 6.7, 6.8, 6.9, 7.0, 7.1
XFree86 4.3 Drivers - Display Drivers for XFree86 4.3
X.Org 6.8 Drivers - Display Drivers for X.Org 6.8

but i dont know which one i should use and how to use it...i mean to install it.
rite know i'm using windows xp for internet. i got problem on setting wireless network on fedora.

[glennzo]

I believe you need kmod-fglrx for your ATI card. Try, at the command line, 'rpm -q kmod-fglrx'. If kmod-fglrx is not installed the outpit will look like this: package kmod-fglrx is not installed, if it is installed it will look like this:

kmod-nvidia-1.0.9631-1.2.6.18_1.2868.fc6
kmod-nvidia-1.0.9631-1.2.6.18_1.2869.fc6

Of course, this is from my own computer, your's will say kmod-fglrx and not kmod-nvidia. However, you say you have no wireless in Fedora, then you should probably fix that before you worry about special video drivers, which you probably won't be able to get without the aforementioned wireless connection anyhow. :D

Glennzo...how am i going to do that? can u point me to something? or mayb teach me step by step. i dont really familiar with fedora or any other linux program. just new to this.

about the wireless...dont bother me for now. i dont feel to use rite know.

One of us is going to have to find some info on the ATI cards here in Fedora Forum. I know that there's been a lot written about the installation and useage of said video card. I bet that someone in the forum will chime in and post a link or two.

Glennzo - I just happened to come across your thread because I too am running an FX5200 card in Fedora Core 6. However, I couldn't get the installer to recognize my card during bootup, so I did the non-gui install. Were you having this same issue?

After installing the OS, I finally got the system to see the right nvidia drivers, but couldn't get it to run in runlevel 5 - only runlevel 3 and then I would have to type startx or init 5 after I login, otherwise the screen also goes black for me, just as this thread suggests. (Although a regular boot worked just once and I'm not sure why.) My system usually stops working right when udev loads. If you have a minute, would you mind looking through what's transpired so far in this thread?:

I looked through the thread and see that you are having the type of trouble that would make me remove the video card and toss it out the window. Do I understand correctly, you are using a TV as your monitor, or are you using the TV out as well as a desktop monitor? At any rate, I'd go back to the original xorg.conf first, then start diagnosis from there. Get the box working, sit back and relax. You'll get it fixed. Keep that original file safe! Here's my xorg.conf for your reference. My monitor is a BenQ T903 19" flat panel.

... Do I understand correctly, you are using a TV as your monitor, or are you using the TV out as well as a desktop monitor? ...


Yes, you understood correctly. The box's function will hopefully be a mythtv box. I was using the svideo out on the FX5200 card (PCI), however I also have a monitor attached to the on-board video adapter. I can't shut that off in the bios, so when it boots up, it actually boots up on the monitor attached to the on-board graphics card. Then, once X starts, it pops over to the TV screen.

Eventually when prices for LCD panels come down a bit, I may hope to pick one up and as you say "toss [the video card] out the window" and go for DVI output on a better supported video card.

Any thoughts as to why it would load windows normally if I have it load runlevel 3 and then do an init 5, as opposed to starting the system directly to runlevel 5? I looked in the inittab and the only item that stood out at me was:


# Run xdm in runlevel 5
x:5:once:/etc/X11/prefdm -nodaemon


Do you think prefdm has an issue with the nvidia driver?

BTW - Thanks for the config file - I'll try it out and see what happens sometime tomorrow... losing too much sleep over this thing! :)

[glennzo]

My inittab is exactly the same. I wanted to add that as well as going back to basics, use the monitor only, get your system stable and then add the TV. Once it's stable I'd copy the xorg.conf and keep it to fall back on if it messes up when configuring the TV.

my kernel :

[glennzo]

If you're talking about installing the video driver for your ATI card, it's version number needs to match the kernel version. Why don't you try 'yum download kmod-fglrx' and see what that get's you? Then let me know what the result was.

[chile712]

i got fedora 6 to boot up after a fresh install on my Ati x1300.
when it boots up press enter at the grub boot screen.
press the key "e" to edit grub remove "rhgb quit" from "kernel /vmlinuz-2.6.18-1.2798.fc6 ro root=/dev/VolGroup00/LogVol00 rhgb quit"
it should look like this after "kernel /vmlinuz-2.6.18-1.2798.fc6 ro root=/dev/VolGroup00/LogVol00" and press enter and the "b" key to boot the temp changes you've made.
next you'll get the first boot screen to come up and enter you info.
after that i got a screen trying to come up but it didnt, so i reboot my computer and let if boot up normaly. i got the out of range on my lcd. i let the computer. once i saw the led on my computer stop and then i new it was at the login. i enter'd my info and i think it was logining in. After that i pressed "Ctrl+Alt+Backspace" till i got the xserver error. then i fedora went through the detect a fresh display process. After that fedora started to work like normal. i no longer get the out of range messege on my lcd.

[el_diablo4303]

isn't "yum download kmod-fglrx" needs internet connection? if its true.....sadly i don't have it.

sorry to tell....i dont have internet connection for my pc with fedora OS yet. i just install livna-release-6.rpm manually. it goes ok i guess...with 2 line say something that i forgot..but it show 100%. after that i import rpm-livna-gpg-key manually. but...nothing happend after that.
i have check on /usr/src/kernels and i found that it kernels is 2.6.18-1.2798.fc6-i586. however when i login as root....something like this appear :

Fedora Core release 6 (Zod)
Kernel 2.6.18-1.2798.fc6 on an i686

Login :


now i'm more confuse with which one is my kernels. is it i686 or i586.

Glennzo...

I got the same probelm as eldiablo4303, and i have followed your guide as far, I boot with add 3 to grub, and edit xorg.conf as you state above.

This is my xorg.conf

# Xorg configuration created by system-config-display

Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"
EndSection

Section "Monitor"
Identifier "Monitor0"
ModelName "AOC SPECTRUM 7Dlr & 7DlrA"
### Comment all HorizSync and VertSync values to use DDC:
HorizSync 30.0 - 68.0
VertRefresh 50.0 - 120.0
Option "dpms"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "i810"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"

SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection

But, when I type startx, I got error message say:
....
...
...
(EE) No screen detected

Fatal server error:
no screens found
XIO : fatal IO error 104 (Connection reset by peer) on X server "0:0" after 0 request (0 known processed) with 0 events reamining.
[root@localhost X11]#

SO, I tried to change the HorizSync to 30-95 and vertRefresh to 50-160, but the same error occur. And then, I tried to rip "1024*768" so my Modes line is :

Modes "800*600" "640*480"

But again, the same error occur, and sometime blank screen.

Hopefully you can give some advice, i get really stuck now after a lot of try.

el_diablo, I ever see on fedora website that there is a bug in anaconda (fedora installer), which one some machine make anaconda install the wrong kernel, so kernel i586 installed on i686 machine.

You can fix this bug by getting the patch for anaconda in fedora bug website.
