video works fine in Hardy, not in Jaunty

[Bunny Boy]

I've installed Jaunty on a computer that has been running Dapper, as a dual boot, but I can't get it to recognize my video card. It will only boot in low-graphics mode, with a series of error messages.

Here is what lshw tells me about the video card:

*-display UNCLAIMED
description: VGA compatible controller
product: KM400/KN400/P4M800 [S3 UniChrome]
vendor: VIA Technologies, Inc.
physical id: 0
bus info: pci@0000:01:00.0
version: 01
width: 32 bits
clock: 66MHz
capabilities: pm agp agp-3.0 bus_master cap_list
configuration: latency=32 mingnt=2

What do I need to do to get this working like it did in Dapper?

That means that the Linux kernel recognizes the graphics hardware, but that the system is unable to configure it correctly.

Post your /etc/X11/xorg.conf in this thread.

OK, here 'tis:

Not much there to work with, eh?

No, not much. Adding different screen resolutions manually to that configuration file can make it broken unless it's done correctly.

If you noted down the configuration file from Dapper, then you could compare those 2 configuration files to easily see what it lacks, but I assume you don't have it, so I guess it's back to google searches then.. :)

In this old thread (http://ubuntuforums.org/showthread.php?t=88374) they discuss this matter as well.

The configuration file looks better there.

Actually, I do have it:

I tried copying it over, but it didn't work.

[Bunny Boy]

I tried to correct the subject line. It should say Dapper instead of Hardy.

Anyway, when I downloaded the driver from VIA, I can't unpack it. -- gunzip tells me that the .tgz is not in gzip format. Any clue?

tar xvfz file.tgz
or

gzip -d file.tgz and then
tar xvf file.tar
should do it.

Anyway, I strongly believe that you need a tool for creating a new configuration file, since it's a newer version of x.org in Jaunty than Dapper, so just copying it over as you did is expected to fail.

About the driver you downloaded, I think it's unnecessary because you already have the driver in the Linux kernel. The driver needs to be used and that's the problem, not that your system is lacking it.

I tried that xvfz, and it didn't work either, still says it's not in gzip format. What tool creates xorg.conf besides dexconf?

I did modprobe via, and then lsmod shows via, but the display still doesn't work.

If you had an video card from ATi or nVidia, the installer package creates a pretty big xorg.conf. I don't know what tool to use, but it seems you're stuck with Dexconf.


man dexconf if you're curious on what it can do.
