Scribbling feverishly on April 13, Klaus-Peter Schrage managed to emit: [loading DRI snipped] Hallo, Klaus-Peter, > After restarting the x-server, voilą: dri. > There are two hitches left with my setup: > - When the kde login shows up, it is barely readable and the screen is > a bit scrambled, but when kde get loaded, the screen looks nice as ever. > - dmesg shows me two two errors: > > mtrr: no MTRR for dc000000,2000000 found This is the Memory Type Range Register (hence, MTRR). In your kernel config file, set CONFIG_MTRR=y and recompile. > [drm:r128_cce_indirect] *ERROR* process 687 using buffer owned by 0 This means that the process numbered 687 is trying to access a buffer owned by the UID 0, which is root. The error is coming out of the DRM code ($KERNEL/drivers/char/drm), specifically r128_state.c. To the degree I understand the code, and I confess my understanding of it is limited, this error occurs in three places. In general, the process is trying to flush some data to keep texture memory intact, but doesn't have root privileges and is causing an error. I'd definitely browse the archives of the Xpert mailing list and see if this has come up before (I'm sure it has) and how to fix it. Kurt -- You are scrupulously honest, frank, and straightforward.
