Re: setting resolution on a second display

Hi Michael,

if you are still there - try the iso I uploaded. The xorg server used in 4.0 let me be gentle, is buggy - there was quite a lot of changes in those times in xorg. That one used now for 5.0 did big improvement.

Second do not trust tazx - check at least if mesa-dri is installed and check all the time /var/log/Xorg.0.log - nothing else tells you about the driver, the display and the error

Third - the sis driver - do not expect with "exotic" hardware, that it works like in windows. I did not check the sis driver, because I have no sis hardware, but I think it could be the same as with my trident driver from the portegee R100 - I never got my external display working with 1600 x 1200 as it works with windows only 1024X768.

the only distributions, that have proprietary support for Sis is Ubuntu and Satux (at least I know) - you may try it with these CDs and you will see what is real possible - http://wiki.ubuntuusers.de/Grafikkarten/SiS - compaere the XorgO.logs will help you

Re: setting resolution on a second display

PC with no AGP slot (even though it loads sis_agp O_o). It's a sis 630/730 onboard card that uses some of the RAM as VRAM. It was also used in Laptops. The pain with it is that xorg defaults to vesa even if you have the sis driver installed. The only way around this is to remove vesa which forces it to use sis instead.

The way I can tell it's using sis properly is that low resolution programs (like running ZSNES at 320x240) display properly where before it used to be misaligned and boxed on the screen (like the monitor was set badly). You also get way more options in the lxrandr program.

Funny enough, it doesn't show up ANYWHERE in Xorg's conf files though.

@kultex

What iso did you upload where? - Tomorrow is my last chance to try it. Thanks, whatever result it will give! ;-)

@kultex

Thanks a lot, I found it and tried it. But it does not work. In case I install sis and remove vesa it does not start a screen. And, more important, my Turkish friends here won't be able to run the cooking version without problems when I not here. So I stick with the given resolution and 4.0.
