finally I have found the origin of the problem, looks like the i915 module can not be loaded , because of a mismatch in the kernel module loading orders, since it was impossible to get /dev/dri/card0
To solve the problem, I compiled a custom kernel setting agpgart and i915 drm in the kernel and not as modules. like this everything works fine , since i915 is not a loadable module. Can somebody forward this bug to the right group (udev ?) I suppose I won't be the single user of an i915 chipset... -- [I915GM] slow desktop refresh poor graphics performance https://bugs.launchpad.net/bugs/514210 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
