Thanks for your help. The link you provided is very useful, although
their advice regarding my problem did not work for me. According to them,
sudo sysctl -w kernel.shmmax=0x7fffffff
should "increase the shared memory permanently." But after reboot on my
Linux Mint Debian system with mdm and bash, the file shmmax has the old
value again.
However, the following link gave me better advice:
http://www.ubuntugeek.com/howto-install-cinelerra-in-ubuntu-gutsy-gibbon.html
I used sudo emacs (any text editor will do) to modify the file
/etc/sysctl.conf with the added lines
# The following line was added to avoid the warning in Cinelerra
kernel.shmmax=0x7fffffff
On some systems you might need to use a slash instead of a period, i.e.
kernel/shmax. See how the syntax goes for the rest of that file, and
follow suit.

Jonathan,
That message means you need to increase the shared memory during your
work session. You will need to this permanently by updating the
appropriate setting.
A search of "cinelerra" and "0x7fffffff" will reveal a few posts
resolving this.
Perhaps Grandma might be a good starting point:

I just installed cinelerra-cv 2.2-dmo5 on my Linux Mint Debian system
with kernel Linux 3.7.0-4.dmz.1-liquorix-amd64.
When I run it, I get a warning message that tells me to echo
"0x7fffffff" to /proc/sys/kernel/shmmax
I have no root account so I used sudo, but then bash prevents me from
accessing that file before I can input my password
I was able to modify the file with sudo emacs, and I entered the decimal
of 2^31 there. I have 4 GB of RAM BTW.
Cinelerra seemed to work fine after that, but when I rebooted, the file
shmmax was back to its old low value.
Is there a login script or something I can modify so that I don't have
to deal with this every time I run Cinelerra?
Should I direct my question to a Linux Mint Debian forum instead?
Thanks in advance.
