xorg nvidia resolution problems with KDE

kevmille · 2008-06-02 17:52:15

I just installed Arch 2008.04-RC last night. I configured xorg.conf using nvidia with the screen resolution set to "1440x900" which worked in both the X Windows and KDE 3.5.9.

I was trying to get xine working with Amarok. At one point, I deleted ~/.xine and xinirtc to force itself to reset. I then rebooted at which point I noticed the resolution set only at "640x400" in KDE. I checked the Display Settings and that was the maximum resolution I could choose. I then switched to the vesa drivers which allowed a maximum resolution of "1024x768".

I removed xorg and nvidia and reinstalled. I can no longer get a resolution of "1440x900" resolution for my Viewsonic VA1926v flat screen monitor. I read on the xorg log that

I am using the Nvidia GeForce 7300 GT video graphics card. uname -r: 2.6.25-ARCH

From /var/log/Xorg.0.log I get the following information when I am using vesa:

(II) VESA(0): Total Memory: 4096 64KB banks (262144kB)
(II) VESA(0): Generic Monitor: Using hsync range of 30.00-82.00 kHz

(II) VESA(0): Not using mode "1440x900" (no mode of this name)
(II) VESA(0): Not using mode "1280x1024" (no mode of this name)
(--) VESA(0): Virtual size is 1024x768 (pitch 1024)
(**) VESA(0): *Built-in mode "1024x768"
(**) VESA(0): *Built-in mode "800x600"

(**) VESA(0):  Built-in mode "320x200"
(==) VESA(0): DPI set to (96, 96)

With nvidia, it just states that no mode is available for '1440x900' and selects virtual size of '640x400'.

I am at a loss at trying to fix this one. Something similar happened when I was running Gentoo on this same desktop back in April. I also have the same low resolution problem when using Sabayon.

Any help here would be much appreciated :-)

From your xorg.conf, I'd say that your monitor was somewhat missconfigured: what did you do when you configured it? Can you look up in the manual and see if the frequency ranges are the ones supported? Is it your hsync really 30-82 kHz and your vertical refresh only 50-75 Hz? I'm no expert on flat screens, but these values seem a bit low even for my 5 years old 17" screen CRT clunker.

I thought these frequencies were a bit low too. My manual said there were the frequencies. I checked online and it said the same. I need to do more research on it.

I did manage to get my 1440x900 resolution back using the open source nv drivers. I had to do the same with Gentoo and Linux Mint in the past. Everytime I used the nvidia drivers, my monitor returns to the 640x400 resolution and I noticed the only way to avoid it was to use nv. I do not play games online or use Compiz so it does not bother me.

Thanks.
