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 ?

Many thanks,

Sergio



Unless you are using some OLD version of Linunx. posix shared memory is
probably already enabled. Type mount and look for /dev/shm.

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 ?

Thanks

S.

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.
