ZMLinuxOS live cd monitor size

[neilk]

well first off downloaded and installed ZMLinuxOS live.
quick edit of modprobe.conf to set card to same has i had working under ZM 1.23.3 on suse 10.1, no big problems working stable and a nice low load on the system.

Main problem is monitor size it will only run if i set size to 384x288 , why ?
under suse and the ZMLive cd 2007 i had 4 cam's running at 640x480 with no problems, apart from a load of 23.5 on the system .

yes i get the shared memory kick in the nut's, but no matter what i set shmall and shmmax to i still cant get a monitor to run at 640x480 they just go red.

and i have read the FAQ's re shared memory but as a linux noob, you may as well talk to me about AI

any help would be very thankfully received

When you set the shared memory in /proc/sys/kernel/shmmax via echo,
Can you see the changes reflected with ipcs -l ?
and since you didn't mention it, did you restart the ZM service after the change?

[neilk]

yes the changes are shown via ipcs -l after the echo'ed changes
i even edited the sysctl. file so the changes were set after a reboot.

as said it seems no matter how much memory change is done , the result stays the same ie unable to set monitor res higher then 384x288

this is after setting monitor res to 640x480, (house-front) Video1

thanks for your time with this Cordel.

how can I fix this shared memory error??

The command ipcs -l shows:
