FC5 Dual Head ATI Radeon 7500 Resolution Issue

Alright, I have a IBM T42 and a Samsung SyncMaster 913v attached through the docking station. I have 2 Issues a solution to either would be wonderful.

When configuring for Xinerama ON and Clone OFF and spanning the desktop through the Display options the gnome-panel stretches across both screens as well as any applications that are maximized (as opposed to the same conf. in FC4 where the gnome-panel only filled the laptop screen my primary and borders were set for maximizing between each physical montior).

Current setup has Clone ON and Xinerama OFF which stops the panel from going across both monitors as well as applications maximizing between both screens, so far this sounds perfect, but this is so because the resolution is set to 2048x768, still sounds good. Here's the issue with this setup......I have 2 different resolution monitors my primary is 1024x768 while I need the 2nd as 1280x1024. With the 2048x768 my secondary (the samsung) is not the resolution I need it to be.

Code:

Any suggestions would be greatly appreciated. Anyone well versed in the ATI drivers arguments for xorg.conf and has time I would like to talk to. Thanks in advance!

Anyone find a fix for this yet?

I noticed I'm stuck at 60Hz now too.

Cheers!

I've a similar setup. T42, Radeon Mobility 7500 and an external lcd monitor w/1280x1024 resolution. I ended up downgrading to Fedora 4 because I couldn't get the dual head setup to work!!!!

But I found a reference to a test driver on one of redhat's servers (credit goes to http://www.redhat.com/archives/rhl-l.../msg02069.html, although I see I'm not the first on this forum to mention it). I've been running FC5 off of an external USB drive for testing and so far it's been working fine. If I make it through the day I figure I'll update my FC4 version to FC5 and rejoice!!!!!!

The driver is at: http://download.fedora.redhat.com/pu...8.0-1.i386.rpm .

You should be able to install with:
sudo rpm -Uvh http://download.fedora.redhat.com/pub/fedora/linux/core/updates/testing/5/i386/xorg-x11-drv-ati-6.5.8.0-1.i386.rpm
...or if you're behind a proxy...

sudo rpm -Uvh http://download.fedora.redhat.com/pub/fedora/linux/core/updates/testing/5/i386/xorg-x11-drv-ati-6.5.8.0-1.i386.rpm --httpproxy myproxyaddress --httpport 8080
(or whatever your proxy port # is)
Here is my xorg.conf:
Code:
# Xorg configuration created by system-config-display

Section "ServerLayout"
	Identifier     "Multihead layout"
	Screen      0  "Screen0" RightOf "Screen1"

If the address doesn't work, the version # may have changed. Make your way to http://download.fedora.redhat.com/pu...testing/5/i386 and take a peek.

Remember that this driver is in the testing directory. Use at your own risk.

Have either of you tried using aticonfig to do the dual-head for you?

I think the command is something like:

Code:
aticonfig --initial=dual-head

I tried all of that stuff and my ATI chip still does not work in the T42. I had it working for about 2 days then when I moved to the 2122 kernel I cannot use the new module for that kernel. It's driving me nuts... Im about to scrap this notebook and buy an nvidia based one as those users seem to have less trouble.

So as of current I cannot use my GL or my dual Head on this notebook. Blah

Wicked....finally FC5 is now officially PIMP. Muchas gracias dacloutier! That ati driver was what I needed have my laptop 1024X768 with xinemara on and the dual monitor at 1280x1024. Had to edit the xorg.conf to force the 2nd head to 1280x1024 other than that it was install the driver. Thanks for the heads up!

No problem. I'm very happy to take credit for other peoples' work!

I've gotten so much help from this and forums like this one that I figure I should return the favor when a solution comes across my desk.

As for the "aticonfig --initial=dual-head" suggestion, I appreciate the help, and it will help others. But according to http://thinkwiki.org/wiki/Fglrx (scroll to bottom of the page), the Radeon Mobility 7500 isn't supported by the fglrx driver. I tried it anyway, but guess which ATI chipset I've got.... yep, the 7500.

Just to confirm that upgrading to http://download.fedora.redhat.com/pu...8.0-1.i386.rpm
allowed dual head to work on my Delll Inspiron 9100 'portable' with an ATI Radeon Mobility 9600 card, the second monitor being a standard LCD monitor.

Once I had upgraded the driver the System->Administration->Display gui easily allowed the dual head to be set up and activated the dual head when you log in again. With the previous driver it would just hang when you tried to restart X with the second monitor connected.

So thanks for this very useful post!

I'd just like to add my thanks to the people who contributed to this thread. I'd been tearing my hair out trying to get "big desktop" going and had not been successful with the fglrx driver nor the radeon driver until I followed dacloutier's instructions above regarding the "testing" driver. I even cut-and-pasted dacloutier's xorg.conf and it worked! I just had to add support for the 1600x1200 resolution of my laptop and external screen. Thanks again to you all.

My set up is FC5 on a Thinkpad R50P which has an ATI Mobility FireGL T2 graphics card and I have a Sony 20.1" LCD monitor - SDM-S204B

I have also been unsuccessful getting the 7500 on my thinkpad to work in FC5 at all. I had it working for a brief period about a month ago, but since then no luck. No matter which driver I seem to install, nothing works. So I feel your pain. Would be nice to use a second monitor like I used to do with Windows.

I'm patiently waiting for an update that will solve this issue for me soon. In the meantime I'm just coping.

Looks like the driver is out of the testing directory. Running "yum update xorg-x11-drv-ati" should work now.
