openSUSE 12.1 x86_64
Video card ATI RV280 5961 Radeon 9200
Monitor Viewsonic VA721
“My Computer” says I’m running the Radeon driver.
My reason for creating this mess is that just after I make my selection on the Grub screen, there is a brief period during which my monitor goes blank and an error message is displayed “Out of Range”. I then see the verbose screen and things work normally.
Or at least they did.
After seeing how easy it was to use the proprietary driver using atiupgrade, I decided to take the plunge to see if I could speed up video response.
Turns out my card is not supported. I didn’t recognize that a 9200 card is not a 9200HD card. Big difference.
So, I ran atiupgrade to remove the proprietary driver and supposedly put everything back to the way it was.
Something is obviously not back the way it was because I lost the screen effects, I lost the verbose screen, the Out of Range message stays until the logon screen is visible, and menus have a distorted background and several other annoying screen anomalies are present.
So, I looked at the sticky about installing and running sax3. I did and the effect was to prevent me from attaining level 5. I booted to level 3, logged in as root and removed the 99* files from etc/X11/xorg.conf.d/ and then rebooted. This allowed me to again access the KDE desktop.
There is obviously something different about my system from before I ran atiupgrade and after. I looked inside all the files in /etc/X11/xorg.conf.d/ and everything inside all of the device and monitor files is all commented out. Is there anywhere else a conf file could lurk?
Is there a way to completely remove all the video drivers and then reinstall just the radeon driver?
What about the error message during boot? I have a “vga=0x31a” in the boot string. I found this by trial and error but have not been able to come up with an actual list of what the octal codes actually mean. My monitor supports only 60 and 75 hz vertical rates at the 1280 x 1024 resolution I want to use… I suspect this is the problem but the octal codes seem to only affect the resolution and not refresh rate. Grub comes up as 1024 x 768. openSUSE runs at 1280 x 1024. Obviously, the problem lies in the resolution switch just as Grub exits and openSUSE starts. Could I configure Grub to load at 1280 x 1024? Would that be in a grub configuration file somewhere? How do I specify refresh rate? Is this something that is set by the automatic video until it reads the boot parameter? Is my boot parameter wrong and is the driver overriding it and setting the proper resolution in spite of me?
I seem to find that the AGP slot in my machine is quite obsolete. Is there anything short of replacing the entire system board and all that I can do? I see an HIS card that says it has a Radeon HD 4670 chip. Would it work?
The good news is though, that this is not Windows and I am confident that I/we will prevail!
