Hello. I am installing drivers for My graphic card Sis Mirage 1 662 (integrated). But terminal writes me this: "You must specify a keyboard in XF86Config" After this output installing script stops. I need to install these drivers because of shadows running on my screen... If someone has experiences with this problem, than please help.

Before anybody can help you, please tell us:
1. What distro you are using;
2. Where did you get the new driver (link);
3. Where your current xorg.conf comes from, was it generated automatically when you installed Linux? Please post "InputDevice" section for keyboard.

I "googled" and I got answer about ltsp server... But I have not server installed and Synaptic tells that it cannot be installed on regular PC.
Anyway distro: Ubuntu 7.10, drivers are from sis.com (but at sis.com there are no linux drivers precisely for my graphic card), yes it was generated automaticaly and what is it "InputDevice"? :-) But anyway I am about to order new graphic card, because now I think the problem has no solution ('cuz of missing drivers for linux and my graphic card). Do you have another opinion?

Well, I'd visit xorg site and find out if this video chip is supported.
If it is I'd check out Ubuntu repositories to see if driver is available thru normal installation procedure. I think Ubuntu has a GUI tool for it. Synaptic or apt-get will do, too.

Edit: What LTSP has to do with this?

Driver installation call LTSP... Why? I don't know... Anyway, when I put the error message into Google I got ltsp homepage troubleshooting... Anyway ltsp through Synaptic gives me error message that it cannot be installed on regular computer. But, is there any other reason, why my monitor is doing so badly? I will describe my problem exactly... I can see vertical stripes on monitor. These stripes are thin copy of screen and are moved a little bit to the right. It's a little better, when I get low my screen resolution. These stripes are not stabil (they look like sound waves but they are vertical) It gets worse, when something on screen is moving...

LTSP is Linux Terminal Server Project. Totally irrelevant. There is Xorg configuration file /etc/X11/xorg.conf. Edit it as root and replace your video driver with "vesa". In Ubuntu something like this:

I did it. It solved the "waves problem" but it has brought another one. The resolution is soooooo... low and it can't be made higher. Also color depth is very bad (256 colors i guess)... Please, how to solve this?

What kind of monitor you have? Put your original driver back and try playing with VertRefresh and HoriSync values in xorg.conf.
For example, something like this for a LCD:

HorizSync 31.5 - 64.3
VertRefresh 60.0

OK. I played with this... This settings have certainly influence on that "waves". When I set lower VertRefresh I get lower waves. But when I want to go lower than 60 on VertRefresh it behave the same way like I was using vesa.

I have LCD 17" Asus MM17D.

I'm running out of ideas. Try limiting HoriSync, your computer is not overclocked, is it? What is your desired resolution?

Overclocked - no
Desired resolution - at least 1024 × 768

The problem is so serious... I will buy a new graphic card and lets hope it's gonna be all right. But thanks for your interest.

SiS stuff isn't too well supported, but it can work. I have a laptop with a barely supported SiS graphics chipset that isn't terrible, no direct rendering though. If you have the option, another video card, such as one from Nvidia, would give a lot less problems.

Hi

SiS drivers can be downloaded from location www.winischhofer.eu/linuxsisvga.shtml. They seem to be more current (2005) than those by SiS (2002). I did not download/install these drivers, as they were included in the distribution and activated without user intervention.
