X.org Resolution Change Problems


Hi,

I'm having issues with X.org. I can't change the screen resolution. I've modified the xorg.conf file more times than i can count. I've used the configuration program. And no matter what I do, the resolution never changes from 640x480.

Yes, the monitor and card are capable of driving the screen at 1024x768, I know becaues I used to run virtual framebuffer console thing.

I'm not sure the specific type of chip inside the computer. It's an IBM Netfinity 5000.

Any help would be appreciated.

Code:
sudo -c '/sbin/telinit 3' # Switch to console mode (may be 2 on some systems)
#... log in ...
X --logverbose 5 # X will start; press Ctrl+Alt+Backspace to kill it
sudo -c '/sbin/telinit 5' # Switch back to GUI (may be 4 on some systems)
You should then get details in logged in /var/log/XOrg.0.log (I think that's the right file for XOrg) with explanations as to why the higher-resolutions are being dropped.

How high can you count? j/k

Maybe if you include the pertinent parts of your xorg.conf we can see what you've done there. Sometimes this is a problem with the horizontal and vertical frequency settings for your monitor in there.

Rjlee: It refused to start X that way, said that option was invalid.

I can't paste the config, since that machine is not on a network, so I'll include the important informatoin

Config:

HorizSync 31.5 - 48.5
VertRefresh 50-70

Section "DEvice"
Identifier "Standard VESA"
VendorName "Unknown"
BoardName "Unknown"

Driver "vesa"

Section "Device"
Identifier "My Video Card"
Driver "vesa"

Section "Screen"
Identifier "Screen 1"
Device "My Video Card"
Monitor "My Monitor"
DefaultDepth 16

Subsection "Display"
Depth 8
Modes "1024x768"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 16
Modes "1024x768"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 24
Mode "1024x768"
EndSubsection
EndSection

I also found out my graphics card name: S3 Trio64V2/DX/GX Revision E.

And parts of /var/log/org.0.log that looked interesting to my newbie self:

(II) VESA(0): Total Memory: 16 64KB banks (1024kB)
(II) VESA(0): Not using mode "1024x768" (no mode of this name)
(II) VESA(0): Not using mode "800x600" (no mode of this name)
(--) VESA(0): Virtual size 640x480 (pitch 640)
(**) VESA(0): *Built-in mode "640x480"

Well, I fixed it sort of. I used the generic S3 drivers, and switched to 8bit, and it does now work at higher resolutions. But, the screen sort of scrambles when X is open , and when I ext it, the text is all messed up, as if the characters were a different set.

Broken drivers?

Is this correct for your monitor?
