Hello People, I just thought I'd share with somebody what I learning upgrading the kernel on my CRUX distribution. Now I might be wrong and I'd be interested to hear from others who have some experience in this area. If not it might be useful to other upgraders, or to those who are working on the next release. The context - CRUX 2.6 - Intel i915 graphics chip on my motherboard - Upgraded Kernel to 2.6.34.1 - Upgraded Xorg server to 1.8.1 - Upgraded i915 X server driver to 2.12.0 - Mesa 7.8.2 - Lib DRM 2.4.21 After upgrading I was having enourmous trouble getting X to start, it kept trying to open the /dev/dri/card0 node and failing. Initial Google searches for this problem suggested that X is responsible for opening this dev node. Looking more into the problem I believe I've arrived at the conclusion. - Since Intel i915 driver version 2.9.0, graphics driver modesretting as changed. Userspace Mode Setting has been removed. Kernelspace Mode Setting is the only option. - The Kernel needs to be compiled with i915 driver, KMS enabled and the fbcon enabled. Also intelagp (agpgart) - I'm concluding that in Crux 2.6 udev configuration assumes that X will be creating the /dev/dri/card0 node, however in this upgrade scenario it is in fact the Kernel that wants to create /dev/dri/card0 and should be responsible for that (can anyone confirm 100%?). I removed the udev configuration supressor line (the comment implies X should be responsible for it) for /dev/dri/card0 and my X problems were solved. - I noted that module argument i915.modeset = 0, while disabling Kernel modesetting, also disables any possibility of 3D acceleration in X. In retrospect this should have been obvious to me. * ubuntu have provided a backported intel 2.9.0 driver for system running 2.6.34 which supports UMS and KMS, thus providing more flexibility for now. I looked into this for myself, but it seemed a little pointless considering KMS is supposedly the future. Although I don't particularly like the default high resoluton console. * I still have trouble with my keyboard and mouse trying to autoconfigure in X from hald, but they work if I force X to configure them. Not sure what's the cause of this yet, but probably totally unrelated to the above. Chris K. chris.kruger@gmail.com
