setting wxga resolution?

[kamina]

How can I set the resolution to wxga? (1280*800) I selected 1024*768 during installation thinking I could just change easily once finished...

[slowhand]

I just added the "1280x800" to the Modes line in Display section of xorg.conf file and restarted the X server.

[kamina]

I did that, but still don't have the option. Maby it has something to do with the monitor I have selected? (lcd 1024*768)

edit. Changed monitor to lcd 1400*1050 and got several new options for resolution. I still did'nt get 1280*800. I went and looked in the xorg.conf and 1280*800 is listed but alot of the visible options are not... :confused:

Which laptop do you have?

It's a Targa Visionary 811 2800+

Mobile AMD® Athlon® 64 2800+
ATI® Mobility® Radeon® 9700 - 128 MB
Chipset VIA K8T 800

Try this modeline
Modeline "1280x800" 83.91 1280 1312 1624 1656 800 816 824 841

Also, on my Toshiba M30, I had to get 3D acceleration working with my nvidia card before 1280x800 would work properly.

Here is my xorg.conf for HP nx7000 with ATI Mobility Radeon 9200.

[kamina]

I copied some of the lines from the .conf file, and after reboot it seems the resolution is like it should be. The strange thing is, that if I go to settings it shows me I'm running at 800*600... Still, everything is smaller and sharper then it was at 1024*768 which makes me believe I'm running at the correct resolution. Possible?

[slowhand]

Which settings are saying you are running 800x600?

[kamina]

The display settings. They still don't show an option for 1280*800...

For the display, can I just type something into xorg.conf or should I figure out a way to install a real driver? It is still set as a generic lcd.

[Varkk]

I think to get that to show 1280x800 you would have to edit the program itself. Also you don't need a driver for the monitor. It should be just fine editing the xorg.conf to specify the settings.

[slowhand]

Varkk is right. My Display settings say 640x480 and don't even offer 1280x800 resolution in dropdown list. If you did get X to run at your desired resolution, forget about what Display settings say ;-)

[kamina]

Uhm...

I took a screen capture from mozilla and the size of the image according to gimp is 1024*719. If you add the toolbar to that I guess my resolution is still only 1024*768...

Try this modeline
Modeline "1280x800" 83.91 1280 1312 1624 1656 800 816 824 841

Also, on my Toshiba M30, I had to get 3D acceleration working with my nvidia card before 1280x800 would work properly.

Thanks Mike!

After searching unsuccessfully for several hours for the solution to getting 1280x800 resolution trunning on an ACER Aspire 2012WLCi (with Intel Extreme Graphics video), this posting did the trick. The two changes I made to the xorg.conf file were to add the modeline to the Monitor section:

Modeline "1280x800" 83.91 1280 1312 1624 1656 800 816 824 841

and add "1280x800" to the Screen section:

SubSection "Display"
Viewport 0 0
Depth 16
Modes "1280x800" "1024x768" "800x600" "640x480"
EndSubSection

(I also added vga791 video=1280x800 to the grub.conf as kernel options, but I don't think that did anything).

Just wanted to post this in case anyone else had this problem.

Hello,

I am completely new to Linux, and I have been reading this forum for awhile. It was a lot of help to configure my Fedora Core 2.

One thing though is that I still can not have a wxga resolution. I tried your tricks by modifying the xorg.conf and restarting, but when I capture a screenshot, it says the resolution is 1024x768.

My graphic card is ati M10

Thank you very much for your help

i have the same problem using a Toshiba Sattelite M30.
What exactly do you refer to when talking about the modeline in the xorg.conf :confused:
i post the lines of my xorg,conf i have changed. But it doesn't make a change to the display resolution.


Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "LCD Panel 1280x800"
HorizSync 31.5 - 48.5
VertRefresh 40.0 - 70.0
Option "dpms"
EndSection

here i edited the modelName line and set the monitor's resolution to 1280 x 800 instead of 1024 x 768.

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 16
Modes "1280x800" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection

in this part i edited the Modes -line

thanx for helping

At the time I did'nt know what fixed it, but now I did a new installation and found that the ati drivers had to be installed before I was able to set it to that resolution. Try installing them (search google for "install ati drivers fedora") and then try again. Reply here if it does'nt work.

[grillmeister_80]

my toshiba works with a nvidia go 5200 graphics card. I installed the kernel module before editing my xorg.conf. but it doesn't work either. :(

Grill,
What do you have for a Toshiba.....? Because my Xorg.conf file might work for you if you have a simalar model to mine. I have a Satelitte P15-S409.....

[lotk]

See: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=122739

In short:
Put this lines to your "/usr/share/rhpl/extramodes" (NOT to the "xorg.conf"!):

# 1280x800 @ 60Hz hysnc: 48.9kHz
Modeline "1280x800" 68.90 1280 1288 1328 1408 800 804 807 816

Then use (in german - don't know what's it in english) "Systemeinstellungen | Anzeigen"
to choice "1280 x 800". Enjoy!
