--- Comment #9 from benjamin.menant+debian at gmail.com ---
The dmesg output reveals these lines:

> [    5.343548] radeon 0000:05:00.0: VRAM: 1024M 0x0000000000000000 - 0x000000003FFFFFFF (1024M used)
> [    5.343550] radeon 0000:05:00.0: GTT: 1024M 0x0000000040000000 - 0x000000007FFFFFFF
> [    5.343552] [drm] Detected VRAM RAM=1024M, BAR=256M

1G VRAM seems to be a wrong value, since my graphic card holds only 256MB,
which seems to be seeing as BAR (what’s that stuff?). 

Anyway, could it be the cause of my problem?

Thank you,
Benjamin.
