For some reason LinuxCNC 10.04 fails to display menu bars yet straight 10.04.3 seems OK.
Also 8.04 seems OK until I launch Axis (sim) and then the lower portion of the display has a load of dark lines across it. If I then close LinuxCNC and (say) open a browser it clears the crappy display.
Any thoughts from the panel?

If you try one of the other GUIs, it OK (sim-tkemc, which might be sim-tklinuxcnc by now)
That probably points to a problem with realtime and OpenGL.

(Axis (and possibly Touchy) use OpenGL, the others don't.)

I had a problem with a Dell monitor with the background theme and black lines would show up across the menus, if I minimized the restored it would be ok... I finally settled on clearlooks and no visual effects and it seems to work now.

From the symptoms I think andypugh may be on to something there although "sudo apt-get install libgl1-mesa-swx11" made no difference.

I run:
# aptitude update ; aptitude safe-upgrade
all the time here and haven't had any problems.
Disclaimer: I run Debian Lenny with a locally built RTAI kernel with a higher version than any my distribution ships.
That may be why it works here for me. So my kernel does stay top on my grub menu and is always the default selection too. But I cannot imagine why it couldn't be made to work with the EMC CD too. If worse comes to worst put a hold on your kernel image.
# aptitude hold linux-image
I don't think never upgrading at all is a very good idea. Some of the fixes released are somewhat important I'd imagine.
