ls -ld shm drwxr-xr-x 2 root root 40 11. Feb 18:26 shm the /dev/shm/ directory is only writeable by root user. the ati-drivers needs write access to this directory, without right access the 3d driver is unreasonable slow. is there a group to which i can add a standard user, so i can do 3d? who's responsable to set the access rights for /dev/shm/? googleearth without shm write access rights: FGLTexMgr: open of shared memory object failed (Permission denied) __FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed!!! googleearth with shm write access: no error message at all and a great speed up. it look's like that the ati-drivers uses this tmpfs for texture maps. udev is udev-104-r9. hopefully this isn't just an setup error on my side, but i couldn't figure out who set's the access rights to /dev/shm/ Reproducible: Always Steps to Reproduce: 1. logon to X as user 2. start googleearth 3. Actual Results: application is really slow. Expected Results: application should render 3d really fast
Not udev bug. You can override this in /etc/fstab via mode= option, see `man mount` /tmpfs) If ATI drivers need to write there, it's pretty much borked and you should complain upstream.
for me permission of /dev/shm is like this: # ls -ld /dev/shm drwxrwxrwt 2 root root 40 11. Feb 17:12 /dev/shm/ with this in /etc/fstab: none /dev/shm tmpfs defaults 0 0
ok. thank you guys! this was a misconfiguration on my side, i totaly missed the /etc/fstab setup for /dev/shm... Now it work's as it should.
