I've noticed a strange problem today: After a reboot, or a re-start of X, there are no problems with any OpenGL applications. However, after the first time I run one, all further attempts to do so fail with the following message:
Error: glXCreateContext failed
X appears to start correctly, and I can find no errors in the log, or anything else in /var/log/messages or dmesg.
Can anyone suggest a cause, or where to investigate further?
The system details are:
Card: GeForce2 MX/MX 400
Video BIOS: 03.11.01.24.00
Card Type: AGP
NVRM version: NVIDIA Linux x86 nvidia.o Kernel Module 1.0-4496
GCC version: gcc version 3.3.1 (Gentoo Linux 3.3.1, propolice)
This is on an Athlon MP SMP system.
