Unclaimed display s3 ProSavage KN133

Asked by ciaopaulo

Hi,

I'm not sure if the display is working optimally on my laptop. System > Preferences > Display gives "Unknown monitor", I can't turn on normal visual effects in System > Preferences > Appearance (Desktop effects could not be enabled) WHen I run lshw I get the following:

paul@paul-laptop:~$ sudo lshw -c display
[sudo] password for paul:
  *-display UNCLAIMED
       description: VGA compatible controller
       product: VT8636A [ProSavage KN133] AGP4X VGA Controller (TwisterK)
       vendor: S3 Inc.
       physical id: 0
       bus info: pci@0000:01:00.0

I thought creating an xorg.conf file might help. I ran Xorg -configure and dropped the created conf file in /etc/X11/ (the file does seem to identify the display correctly:

Section "Device"
        ### Available Driver options are:-
        ### Values: <i>: integer, <f>: float, <bool>: "True"/"False",
        ### <string>: "String", <freq>: "<f> Hz/kHz/MHz"
        ### [arg]: arg optional
        #Option list removed...

 Identifier "Card0"
 Driver "savage"
 VendorName "S3 Inc."
 BoardName "VT8636A [ProSavage KN133] AGP4X VGA Controller (TwisterK)"
 BusID "PCI:1:0:0"
EndSection

However this has had no effect.

The system does seem to be displaying in 1024x768 screen resolution. So it's almost right.

Computer is Packard Bell iGo 5461.
Running 9.10 (2.6.31-20-generic)

Thanks for any help,

Paul

That didn't work. got an "(EE) failed to load module savagefb" before login screen.

I then get to diagnose or use low graphics (incidently, low graphics just dumps to a black screen - thats another problem for another day)

I edited the Xorg.conf back to "savage".

For the record, savagefb is a kernel framebuffer driver, that can be loaded with "modprobe savagefb" before starting X. You can then only use X with its "fbdev" driver. "Visual effects" (compiz) can not be used on the savage cards.

Thanks, I'll give that a go, but it may be some time before I can get onto the laptop in question.

Well, I am not suggesting any framebuffer driver will help you. You can not use "Desktop Effects" on these cards in any case, the hardware is too limited. Using the normal, default Xorg driver (without any xorg.conf) should give the best results. If the resolution comes up in 1024x768, what is then the problem?

Can you help with this problem?
