By the way, the same behavior has been reported in bug #432256. It is the same bug. gdm does not work, xscreensaver too... Which xserver-xorg-core and drivers are you using on all these machines?

retitle 431746 Xorg/sparc: Xinerama active, but = 0 screens? thank you BERTRAND Joël wrote: I have tested some configurations to isolate parameters : 1/ sparc32/smp SS20 + CG14 - bug (I haven't tested with CG6 because my test workstation has no empty Sbus).

Unfortunately, I don't have access to any machine like this. You said earlier: All program that test Xinerama crash because XineramaIsActive returns TRUE _and_ XineramaQueryScreens returns a NULL pointer and a number of screens =0. Maybe the bug is in XineramaQueryScreens ? So I guess the next step would be to check the return values of these functions on your i386 machines? Then, it will probably be a good time to forward the bug upstream (unless you want to rebuild the server with some debugging printf to find out what's going on in the internal functions). By the way, when you say = 0, do you mean 0 ? Brice

Unfortunately, I don't have access to any machine like this. If you want, I can open an account on a U2 (dual UltraSPARC II/300 MHz with 2 GB and a Creator3D fb). You said earlier: All program that test Xinerama crash because XineramaIsActive returns TRUE _and_ XineramaQueryScreens returns a NULL pointer and a number of screens =0. Maybe the bug is in XineramaQueryScreens ? So I guess the next step would be to check the return values of these functions on your i386 machines? Maybe, but I don't have decent i386 to rebuild xorg from scratch (only K6-III/400 with 256 MB, other i386 are laptop, and I cannot use it to test). Then, it will probably be a good time to forward the bug upstream (unless you want to rebuild the server with some debugging printf to find out what's going on in the internal functions). I can, if that can help you. By the way, when you say = 0, do you mean 0 ? No, = 0. This message comes from /var/log/syslog and is returned by gdm. Regards, JKB
