[opensuse] Posix Shared Memory - for ATI Drivers - Network card issue
Hello there, I have read on the ati website that in order to install properly the graphics card drivers I need to have enable the posix shared memory feature http://ati.amd.com/support/drivers/linux/linux-radeon.html I followed the instructions below quoted To enable POSIX Shared Memory on your system, perform the following as root: 1. Add the following line to /etc/fstab (if it isn't there already): tmpfs /dev/shm tmpfs defaults 0 0 2. Mount shared memory as follows: mount /dev/shm 3. Issue the following command to check that it mounted properly: mount | grep "shm" If the mount was successful, then the following output (or similar) should appear: tmpfs on /dev/shm type tmpfs (rw) and the result appeared as it stated above. But after I edited the /etc/fstab file adding that line and having restarted the system the outcome was that the ethernet card was deactivated. On my adsl modem the ethernet light was off, and therefore no internet connection. In the meantime I removed that line from fstab. Any suggestion on how to enable the Posix Shared memory feature and keeping the network card working ?

Unless you are using some OLD version of Linunx. posix shared memory is probably already enabled. Type mount and look for /dev/shm. -- kr -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I am using Opensuse 10.3 I typed mount, and this is the outcome sergei@linux-tango:~> mount /dev/sda3 on / type ext3 (rw,acl,user_xattr) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) debugfs on /sys/kernel/debug type debugfs (rw) udev on /dev type tmpfs (rw) devpts on /dev/pts type devpts (rw,mode=0620,gid=5) /dev/sda6 on /home type ext3 (rw,acl,user_xattr) /dev/sda1 on /windows_C type fuseblk (rw,noexec,nosuid,nodev,noatime,allow_other,default_permissions,blksize=4096) /dev/sda4 on /windows_D type fuseblk (rw,noexec,nosuid,nodev,noatime,allow_other,default_permissions,blksize=4096) securityfs on /sys/kernel/security type securityfs (rw) Is any of these lines saying that it's enabled ?

Sorry. Unfortunately newer systems evidently don't mount /dev/shm in the same fashion as older systems do, possibly because now /dev itself is mounted as a tmpfs. Not sure. However, I would be very surprised if your 10.3 system doesn't have posix shared memory capabilities enabled. -- kr -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

<snip> I don't think any of that was necessary. Any modern distro, suse included, comes with shared memory already set up and ready to go, so there's no need to go through any of the contortions outlined at the URL you referenced. Disclaimer: I use only intel and nvidia video, hopefully some ATI users will help you undo the damage and get the drivers installed correctly.

But reading again the fstab line above, "/dev/shm" is the mount point, not the device node to mount somewhere else. Thus, opensuse 10.3 already comes with '/dev/shm' mounted, but it doesn't show in the command mount, it must be done in some other way. So... those instructions are incorrect, and we do have that posix shared memory thing. If the driver says otherwise, the driver must be old. - -- Cheers, Carlos E.
