Comment xrandr 1.2+ breaks multi card support in X (Score 1) 410
My desktop is frozen at Debian Etch.
I have a triple head setup with three graphics cards. It has been working well for me for years, though it was a bit tricky to set up. About halfway through the Lenny release cycle, an upgrade hosed my multi head setup.
The culprit was xrandr replacing xinerama. The new code can handle multiple outputs on a single card but cannot yet use more than a single card.
The xrandr code is a definite improvement. No more screwing around with xorg.conf is great. The ability to change screen arrangements and resolutions dynamically is a major win for laptop users. Dropping multiple card support however, is a major regression.
At this point it is looking like I will need new hardware by the time this is fixed. I suppose I can throw a bunch of money at a graphics card with three or more outputs. I got the three cards I'm using now at swap meet prices, I don't relish the thought of shelling out big bucks for a fancy card, I'm just looking at a bunch of xterms anyway.
For now, I'm stuck with an increasingly obsolescent operating system because the X developers didn't thing it was a big deal to remove functionality.
