[SOLVED] Driver for Radeon 7000/VE

noeldum · 03-25-2010, 05:12 PM

I have a machine with an ATI Radeon 7000/VE graphic card and I can not get the screen resolution I need. This is running on redhat enterprise 4 OS (32bit).

My monitor is a 1600x1280 but I can not get anything better than 1024x768.

I did set the desired resolution in the xorg file.

I guess this would rather be a driver issue? I am running with radeon driver at the moment. I tried to get the fglrx from ATI but they do not seem to give any linux support for this card.

Do you now where I could find find the appropriate driver. Or is there any solution to this problem?

fglrx never supported that card. Radeon *is* the appropriate driver. Please show us your /etc/X11/xorg.conf and /var/log/Xorg.0.log files.

Thank for confirming the radeon driver is the one I need.

I put here the xorg and log files. I have tried various think that I have left commented in the xorg.

For the moment I am just concentrating on getting it to work in 1280x1024. But it looks like my monitor is actually capable of 1920, it's a 24". I can see the X log file says the mode I have chosen is out of range.

Surely it must be possible to get higher resolution than 1024x768 on this setup. It was the case with a redhat 9 distro before I formatted all for rhel4. I regret I did not backup the old xorg file.

I have now sorted my problem.

The radeon 7000 does work at higher resolution than 1024x768. I have finally got mine configured at 1920x1200. This is how I fixed my problem:

Using gtf generate the timing information to input in the xorg.conf file.

Code:

gtf 1920 1200 60

This gaves:

Code:

# 1920x1200 @ 60.00 Hz (GTF) hsync: 74.52 kHz; pclk: 193.16 MHz
  Modeline "1920x1200_60.00"  193.16  1920 2048 2256 2592  1200 1201 1204 1242  -HSync +Vsync

I then pasted that line in the monitor section of the xorg.conf file.

Then in the device section I added the following line:

Code:

Option       "PanelSize" "1920x1200"

and set my resolution accordingly in the Screen section.

I hope that will help anyone having the same problem.

Thanks adamk75 for your advice on the driver.
