Howto finetune hardware (audio+video) on a i1100Z (smartbook) laptop with Ubuntu


I'm using my laptop (smartbook i1100Z) for about a year now. The only thing I did was manually get the sweex WIFI card to work. Further I just updated the system whenever updates were available.
So everything is working...
Still somehow I have the feeling both my video and audio are not really working at top performance. The video is slow and audio doesn't sound very well. Could be the laptop(hardware) but maybe it's just not finetuned. Is this possible in any way?

The best way to start were to tell us what kind of video chip do you have (post output of 'lspci' command) and how does your xorg.conf (or whatever your X config file is called). You may also want to check whether cpu frequency scaling is enabled (try to run 'cpufreq-info').

Best,
Ott

Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
no or unknown cpufreq driver is active on this CPU

I'm not sure what to do with the xorg.conf file. There's actualy two of them (?). What should I look for? I'll take a look at the wiki tot see if I can find any info on it.

Found graphics controler: SIS M661MX

Thx so far,
Peter

1) do you have the file /etc/X11/xorg.conf? If yes, post it. IF not, post the list of files in /etc/X11

2) You have SIS 661/... graphic controller. Googling around suggest it does not have a good (=3D) graphic driver. You may try either 'sis' or 'vesa'.

3) What processor do you have? (Post /proc/cpuinfo). It either does not support freq-scaling, scaling is unsupported, or you have to load explicitly the corresponding module.

Best,
Ott

The cpuinfo file seems to be empty.

You're right about the videocard.
The video capabilities of this laptop are not outstanding.
At this moment the screensavers with 'extra effects' are shown very slow.
And I was wondering if this could be improved.
As well as the sound quality.
It sound very hollow... but then: it was a non expensive laptop

I'm gonna buy a new machine this weekend. To use in combination with my LCD TV.
A good opportunity to practice my linux skills some more.

OK. You use 'sis' video driver. Try to google around to check which capabilities are supported. 3D and friends arent, AFAIK (this makes special effect very slow too). You may also check the file ~/.xsession-errors and look for any error message related to glx module (glx is the 3D acceleration module).

/proc/cpuinfo -- I cannot believe it is empty.

New machine -- I would prefer intel or nvidia chipsets.

Best,
Ott

Ok thx for the info, I'll do some google-ing around.

I took another look at cpuinfo, It really is zero kb and keeps giving me this message when opened in gedit:

The file proc/cpuinfo changed on disk.
Do you want to reload the file?

I made a screenshot, can I somehow show this on LQ?

Peter
