Hi to all,
this topic is to require some help as I've tried pretty much I knew about tweaking xorg to get it to work. I have installed Ubuntu on a HP DC5750 computer which sports an integrated ATI Radeon Xpress 200 video card.
My goal is to make it work by giving a proper resolution/refresh rate/depth to the ViewSonic E771 CRT that's plugged in. IF I can have 3D rendering support it will be a plus, but it's not mandatory in any way. This computer is not mine, so I can't modify it any way I want; plus, I don't want to invest in any way neither in a "public" computer. Linux is ther because Windos doesn't know how to deal properly with 3GB RAM.
Currently, it seems that the computer either starts with xorg.conf.failsafe
. The resolution at this time is an ugly 800x600@60Hz@16bits. If I modify the "Virtual" size of the xorg.conf.failsafe then restart the X server without
rebooting, it goes up to 1280x1024, still at 60Hz+16bits. The other resolution provided is an impossible 1024x768@85Hz. I just want it to use 1152x864@75Hz@24 bits, as it did under Win XP.
I tried: to install the proprietary fglrx drivers through the restricted drivers updater in Ubuntu; de-installed them, rebooted, tried with EnvyNG; same result. It still starts with vesa driver and
ati driver (I don't know where the two driver come from, maybe on for each of the display ports). However, the restricted drivers manager indicates that fglrx is loaded and activated (which obviously it's not, seing the miserable, fairly constant 500fps I get in glxgears.)
I also tried to force a bigger virtual screen size in xorg.conf, trying to fool the vesa driver it has a bigger screen plugged in; no result. No result either when I just tried to rebuild the xorg.conf from scratch using .failsafe as a template, adding each line by hand.
Now I've run out of niooB's way of doing things.
Well, I know that the Xpress 200 is very tricky to get to work in Linux, but so far the solutions that some people applied to solve the problem were either too old to be applied here, or didn't worked for me.
Any help is welcome, this 60Hz rate is burning my eyes
