I have Gigabyte Radeon 9200 card (pci id 0x5961). When attached to dvi port, my display (AOC LM919 tft), occasionally exhibits all kinds of wierd behaviour when serving certain apps: 1. Thin white lines striking to the right (mostly QT based apps, like konqueror or kdevelop). 2. Display turns off and on alternatively (same apps as before + some LessTif apps, like djview and xpdf). 3. Display become diagonalized and rotated to left (mostly caused by xpdf). All this problems can be temporarily resolved by closing the offending application (and sometimes switching to and from text console to restore display). Interestingly enough, there are apps that never cause such things - older Athena based apps (xv, gv), most gtk based apps (though mozilla flash plugin causes them when activated) and xine (full screen movies run fine). I have the same problems on Win XP but with much lesser extent and mostly with two apps (IE and Adobe Acrobat; Adobe Indesign, for example, never does such things, while it obviously shares much of the design with Acrobat). On the other hand, Vesa X server always works fine (I've never seen any of the mentioned problems with it). ATI fglrx server (both 3.7.6 and 3.9.0) fails to enable the dvi head at all (the server runs and responds, but display remains black). VGA head always works fine. The same problem is present in XFree86 4.3 and 4.4 radeon drivers. Server options "DisplayPriority" and "DDCMode" help a little (by reducing a frequency of artifacts, while not eliminating them). My machine conviguration: P3 - 600MHz Intel 815 chipset 512 MB ram Gigabyte Radeon 9200 VIVO + 128MB AOC LM919 panel attached to DVI head running in default mode (no modelines in XF86Config).
I am having similar problems. using xorg 6.7.0 radeon driver using dual heads (CRT and DVI-LCD) GigaCube Radeon 9200 SE 128MB SiS 741 chipset 1GB ram (128MB reserved for sis onboard graphics, not working) kernel 2.6.7rc2-mm2 (needed for sis agp support) dri is working 2d works fine, but anything opengl give horizontal lines and flickering (eventually, the LCD gives up and goes black). This includes all gl screensavers and glxgears. I also tried the fglrx driver and the LCD remains black.
switching to a Saphire Radeon 9200 64MB card (non SE) appears to solve my problem. This seems to be a case of overly agressive settings for the cheaper radeon cards.
I ran a few test with Quake 2 (glx+dri) and found no problems. So my problems are probably confined to 2D domain. If what are you saying is true (and I hope so) it will not be too hard to change the timing parameters to something more acceptable.

Stupid Bugzilla... These belong on bug 707... Sorry everyone :/
