I'm getting this same problem, but with one difference: my icons are all spread out vertically. They're much farther apart than they were before.
The thing is, I don't know if it's as simple as a nouveau bug for me. It had been working properly for months. I went away for vacation for ten days, without turning off my computer or even logging out; and when I came back, all my icons were invisible. 01:00.0 VGA compatible controller: nVidia Corporation G96 [Quadro FX 380] (rev a1) (prog-if 00 [VGA controller]) Subsystem: nVidia Corporation Device 063b Flags: bus master, fast devsel, latency 0, IRQ 16 Memory at fa000000 (32-bit, non-prefetchable) [size=16M] Memory at d0000000 (64-bit, prefetchable) [size=256M] Memory at f8000000 (64-bit, non-prefetchable) [size=32M] I/O ports at ec00 [size=128] [virtual] Expansion ROM at fbe80000 [disabled] [size=512K] Capabilities: <access denied> Kernel driver in use: nvidia Kernel modules: nvidia_current, nouveau, nvidiafb unity --reset and unity --reset-icons seem to have just made it worse (because now I can't find my terminal or chrome buttons). ** Attachment added: "Screenshot (see left hand side)" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/762478/+attachment/2798569/+files/Screenshot%20at%202012-03-01%2014%3A16%3A19.png -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/762478 Title: [nouveau] No icons shown in unity launcher when using experimental mesa drivers To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/762478/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
