Hi, not sure if this is the right place:
On FC5test3 with Xair (all updates as of today) DRM fails strangely:
| [ralph@logout ~]$ glxinfo
| name of display: :0.0
| libGL error: open DRM failed (Operation not permitted)
| libGL error: reverting to (slow) indirect rendering
| display: :0 screen: 0
| direct rendering: No
When "straceing" glxinfo, I see the following:
| stat64("/dev/dri", {st_mode=S_IFDIR|0755, st_size=60, ...}) = 0
| stat64("/dev/dri/card0", {st_mode=S_IFCHR|0600, st_rdev=makedev(226, 0),
| ...}) = 0
| open("/dev/dri/card0", O_RDWR) = 4
| ioctl(4, DECODER_SET_PICTURE, 0xbf96c3e0) = -1 EACCES (Permission
| denied)
| ioctl(4, DECODER_GET_CAPABILITIES, 0xbf96c3e4) = 0
| ioctl(4, DECODER_GET_CAPABILITIES, 0xbf96c3e4) = 0
| close(4) = 0
| geteuid32() = 500
| stat64("/dev/dri", {st_mode=S_IFDIR|0755, st_size=60, ...}) = 0
| stat64("/dev/dri/card1", 0xbf96c200) = -1 ENOENT (No such file or
| directory)
| geteuid32() = 500
| stat64("/dev/dri", {st_mode=S_IFDIR|0755, st_size=60, ...}) = 0
| stat64("/dev/dri/card2", 0xbf96c200) = -1 ENOENT (No such file or
| directory)
| geteuid32() = 500
| stat64("/dev/dri", {st_mode=S_IFDIR|0755, st_size=60, ...}) = 0
| stat64("/dev/dri/card3", 0xbf96c200) = -1 ENOENT (No such file or
| directory)
[...]
| stat64("/dev/dri", {st_mode=S_IFDIR|0755, st_size=60, ...}) = 0
| stat64("/dev/dri/card253", 0xbf96c200) = -1 ENOENT (No such file or

| geteuid32() = 500
| stat64("/dev/dri", {st_mode=S_IFDIR|0755, st_size=60, ...}) = 0
| stat64("/dev/dri/card254", 0xbf96c200) = -1 ENOENT (No such file or
| directory)
| write(2, "libGL error: open DRM failed (Op"..., 55) = 55
| write(2, "libGL error: reverting to (slow)"..., 52) = 52
| futex(0x78a5a4, FUTEX_WAKE, 2147483647) = 0
So it seems to open the first card at dri/card0, fails with
DECODER_SET_PICTURE and then tries all other possibly available cards
until it bails out with open DRM failed.
TIA,
Ralph
