State of ATI RS482 gfx driver

Recently my machine got series of instability problems. Current situation is — machine stable if Geforce 6600GT card removed. But this leaves me with ATI RS482 on-board graphics… And this chipset just suxx!

I use free driver — ‘radeon’ one. Does it works? Sort of. Problems noticed:

  • lack of EDID reading — so my 22″ lcd panel works in 1280×768 mode instead of 1680×1050
  • unreadable screen after switching to VT
  • X11 crash if qemu/SDL started
  • X11 crash if MPlayer with ‘x11′ driver used
  • X11 crash if VirtualBox started any virtual machine

Is it usable? Only if there is no other way. But I will rather work on getting my Geforce card working again then trying to get that ATI crap working properly.

TIP: to get 1680×1050 resolution working few commands needs to be run:

xrandr --newmode "1680x1050R"  119.00  1680 1728 1760 1840  1050 1053 1059 1080 +hsync -vsync
xrandr --addmode DVI-0 "1680x1050R"
xrandr --output DVI-0 --mode "1680x1050R"

Anyway according to XRandR there are no monitors connected at all:
