Same here, irrespective of whether Opera is installed or not. In my case the problem always occurs sometime after login on battery power and sometimes (but less frequently) on AC power. I ran 11.4 before on the same machine, absolutely problem free.
I have tried a all the suggested workarounds and none of them works. I could 'live' with the 'appearance issues' but for me the most critical part is that the power indicator stops working when the error kicks in. In turn, it happened on several occasions that while I was running some urgent jobs on my laptop the computer just shut down. Now, given its low priority is there any hope for a fix or is a downgrade unavoidable? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/859723 Title: Nautilus appearance without colour or theme Status in “nautilus” package in Ubuntu: Confirmed Bug description: I started Nautilus.
