Are there any specific x11perf tests I should be looking at? Or should I just script the run of all supported tests? There are many. :-) I'm looking into intel-gpu-tools too. Btw: how can I find out if the GPU is stuck in a low power mode? -- Mihai Donțu _______________________________________________ [email protected]: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.x.org/mailman/listinfo/xorg Your subscription address: [email protected]
