KVM Switchbox / Black Screen / only 1024x768

English Hardware
#1

Hello, i got 2 problems with my openSUSE PC, and im not so familiar with linux (i only use some specific features) so i dont wanna destroy anything with playing around with settings.

Mainboard: ASUS P5G43T-M Pro
Onboard Grafic: Intel GMA X4500
Chipset: Intel G43/ICH10

1) My openSUSE pc is connected to a KVM switch-box. When i start the PC i see the Bios messages and after few seconds the monitor goes to “standby” mode and i only get a black screen. As soon as i switch to a different PC on the switch-box, and switch back to the Linux PC i get a picture and the mouse starts to work to (I can live with this problem, but maybe someone knows a fix for this small problem?)
**
2) **The second problem is bit more complicated, i cant set the resolution to anything else then 1024x768. At “Configure Desktop” at the system settings at “Size & Orientation” it says monitor: “default” and Size: “1024x768”. I cant change anything at the drop-down menu, same for the refresh rate, is at “auto”.
I already googled a bit and i found this directory /usr/share/X11/xorg.conf.d/ but i only got there this one file: 10-evdev.conf
Content:

Section “InputClass”
Identifier “evdev pointer catchall”
MatchIsPointer “on”
MatchDevicePath “/dev/input/event*”
Driver “evdev”
EndSection

Section “InputClass”
Identifier “evdev keyboard catchall”
MatchIsKeyboard “on”
MatchDevicePath “/dev/input/event*”
Driver “evdev”
EndSection

Section “InputClass”
Identifier “evdev touchpad catchall”
MatchIsTouchpad “on”
MatchDevicePath “/dev/input/event*”
Driver “evdev”
EndSection

Section “InputClass”
Identifier “evdev tablet catchall”
MatchIsTablet “on”
MatchDevicePath “/dev/input/event*”
Driver “evdev”
EndSection

Section “InputClass”
Identifier “evdev touchscreen catchall”
MatchIsTouchscreen “on”
MatchDevicePath “/dev/input/event*”
Driver “evdev”
EndSection

If someone has the time to help (i don’t wanna steal some time from someone) and knows maybe how to fix this in noob-language i would greatly appreciate it. Im still on openSUSE 12.2 but I’m already downloading 12.3, maybe it works after the update? I will install it later i will for sure reply here. thanks a lot for reading this, kind reagrds, Michael

I might try and see if a /etc/X11/xorg.conf file exists and if it does, rename it and restart openSUSE. We do not need this file any more. Monitor settings should be made to the file /etc/X11/xorg.conf.d/50-monitor.conf, if required. I assume you are using a VGA connection? If you have DVI as an option, you should use it. Have you tried to bypass the KVM switch and connect the monitor directly to the computer to see if it is a KVM switch problem?

Also, please post future file contents into code # tags using the advanced message text editor if you can please.

Thank You,
