Top and buttom panel missing in Natty

[JohnFante]

I am running 11.04 classic Ubuntu with effects.

The last couple of days my bottom and top panel are missing on every second or third boot. I reboot and it is there again.

See attachment for a visual. I have an idea that Compiz is involved but any suggestions?

Thank you in advance.

Although the issue has likely to do with Compiz, the actual cause is most probably an issue with the video driver or a misconfiguration of those.

For example, if I don't have the following option in the "Screen" section of my xorg.conf for the proprietary "nvidia-96" driver, I have exactly the same issue, but also to the same extent an issue with the desktop handling of Nautilus.

Option "AddARGBGLXVisuals" "True"If that doesn't fix that already, please give some details about your video card/chip and the running video driver.

As a workaround, you could place a launcher on your desktop for the command:

killall gnome-panelGreetings.

Thank you for the reply.

I have added:


Option "AddARGBGLXVisuals" "True"

to the screen section. Hope it helps.

I am using a KVM-switchs that shuts of some off the signal from my monitor, so I am using a edid.bin file to solve that. As far as I can see that is the only "strange" thing about my xorg.conf. See below (before above code was added).

Any suggestions for improvements will be highly appreciated :-) For instance my Logitech MX cordless mouse sometimes behaves a bit strange/slow. I am not sure if that is hardware problem but maybe it is related to my xorg.conf.

My card is a Nvidia GTX275. I am using the drivers supplied with Natty. I have added the X-updates PPA, but they have so far not updated the drivers.

I really don't think that that matters. It's more of an on/off thing with that. ;-)

You could spare your input devices in your xorg.conf to rule that out. I do that, too, no issues by doing so. I modified your xorg.conf regarding that, see below.

I guess you are running the "nvidia-current" driver!?
If so, trying "nvidia-173" would be an option.

Thank you very much. Since I added


Option "AddARGBGLXVisuals" "True"

the panelproblems have disappeared and the other xorg.conf modifications have improved my mouse a lot.

:-D

Glad to hear! :-)
