View Full Version : [xubuntu] Changing screen resolution after basic install

I wonder if anyone can help please?

I have a strange 'combination' PC which is basically a combined monitor and PC, like a 'laptop on a stand'. This is badged as a Vulcan 4021 for John Lewis and also has a manufacturer's code LP200SC.

It has a 1GHz processor with 256 Mb of RAM, plus a 1024 x 768 LCD screen & the display adaptor is an SIS630.

Any attempt to run Xubuntu 9 either via a LiveCD or install using the default options resulted in the screen not being identified and a poorly timed partial desktop appearing in a 2" stripe down the LHS.

However using the second on-screen option for a basic installation, all went well.

So my question: Is there a way I can edit anything to permit the display to be changed from 800 x 600 to 1024 x 768? Currently the only screen option is a single 800 x 600.

If it helps, I have tried a variety of smaller Linux installations and with the exception of DSL, they all come up with a warning about the SIS630,

"SIS630 comp. bus not detected, module not inserted.".

Can anyone please advise? Many thanks for reading this!

well googling around SIS chipset with linux, let you know about some issues. That said:

- the driver you need: xserver-xorg-video-sis
- the distro you need: something light like Lubuntu or puppy (as you dont have much ram)
- forget about 3D (compiz/unity)
- not sure about the best kernel to use: maybe one from Hardy
- inside xorg.conf : set sis instead of vga

No luck, I'm afraid.

The Package Manager confirmed that the drivers 'xserver-xorg-video-sis' were already installed.

Modifying xorg.conf from 'vesa' to 'sis' resulted in a return to the same old problem of a 2" wide strip on the LHS of the screen. Correct resolution, but fuzzy, flickering and shooting off the LHS of the display!

Does this mean we are stuck with a dreadful 800 x 600 display on a 1024 screen because of hardware limitations?

What is strange is that DSL doesn't have a problem - and is the only one that works. I don't really want to use that because the PC is intended for a female and Xubuntu has a very nice visual. DSL is wonderfully functional but pretty it aint!


I take your point re small memory, but for just browsing and occasional email, speed seems very acceptable - better than XP!
