From Windows XP, impressed by the guis created by katja & sonofsol, I move to my music machine booting UbuStu 64 on the -rt 2.6.33-4 kernel. Known issues with my onboard ATI Radeon graphics card - since I haven't used GEM, I haven't cared.
[gemwin] does not work. Cannot create const context, Bad request, peril, peril!
Boot on -preempt 2.6.32-3. [gemwin] works, not tested any further.
Shall I upgrade my graphics card sooner than I had planned or slog through fixing the driver? The drivers may not even be the problem - I have little understanding of kernel intricacies.
A fix so that I can keep my present kernel?
Switch to the best -preempt or a different hard real time kernel?
