faf7dfa099f5b42a703313fbd1bf8afdad07a179, which seems to solve that
Unfortunately, like the hydra, this gave way to more problems.
Remember I have a dual-card triple-head Zaphod setup, so the heads
are 0-0, 0-1, and 1-0, where the latter is the first and only head
on the second card. Both cards are Radeon 9200:
00:0c.1 Display controller: ATI Technologies Inc RV280 [Radeon 9200 PRO] (Secondary) (rev 01)
01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200] (rev 01)
1. The 1-0 head has plenty of weird pixelation errors, making fonts
only barely readable
2. X (as well as console-setup on tty) seem to believe the screens
are taller and place the bottom edge below the physical edge,
meaning I cannot see the bottom centimetre or so. Auto-adjust
does not fix this on any of the heds.
3. When moving the mouse from head to head, the "old" pointer is
left on the edge of the head we just left, and stays there while
a "new" pointer moves about on the entered head. When moving
back, the "new" pointer stays at the edge, and the "old" pointer
4. Switching to tty1 causes screen corruption and the tty is
actually never displayed. Switching to X on :0 (I used :1 to
test) restores heads 0-0 and 1-0, but head 0-1 stays black --
until I reboot.
It feels like progress, but it's not where I need to be yet...
I now have a good feeling of the software and can easily test
commits, so if you have anything...
