When I want to start Xorg again I get the following error message: ... [ 12711.547] (II) [KMS] Kernel modesetting enabled. [ 12711.548] (WW) VGA arbiter: cannot open kernel arbiter, no multi-card support [ 12711.548] (II) RADEON(0): Creating default Display subsection in Screen section "Default Screen Section" for depth/fbbpp 24/32 [ 12711.548] (==) RADEON(0): Depth 24, (--) framebuffer bpp 32 [ 12711.548] (II) RADEON(0): Pixel depth = 24 bits stored in 4 bytes (32 bpp pixmaps) [ 12711.548] (==) RADEON(0): Default visual is TrueColor [ 12711.548] (==) RADEON(0): RGB weight 888 [ 12711.548] (II) RADEON(0): Using 8 bits per RGB (8 bit DAC) [ 12711.548] (--) RADEON(0): Chipset: "ATI Radeon HD 3300 Graphics" (ChipID = 0x9614) [ 12711.548] (II) RADEON(0): PCI card detected [ 12711.940] (EE) RADEON(0): [drm] Failed to open DRM device for pci:0000:01:05.0: No such file or directory [ 12711.940] (EE) RADEON(0): Kernel modesetting setup failed [ 12711.940] (II) UnloadModule: "radeon" [ 12711.940] (EE) Screen(s) found, but none have a usable configuration. [ 12711.940] Fatal server error: [ 12711.940] no screens found I have to manually run "mdev -s" to restore the /dev/dri/card0 device. This happens with an Radeon RS780 and Xorg version 1.13.0 running the latest git kernel. /sys/class/drm/card0/device/power_profile is set to "auto" Is this a known problem? Are there any workarounds? -- Markus
