At work I use Linux, or to be more precise, Ubuntu 12.04. I’ve had all kinds of problems with it and I thought that it’d be nice to track them by making a list. I’ve included the things that I’d really expect to just work by this point.
Recently solved problems
Firefox menus stopped working. When you started the browser, everything would work just fine, but after a while the menus and drop-downs would stop opening. I think it is a known bug in Firefox. It disappeared a while ago, maybe after some software update. Update 2014-04-18: It’s happening again. :(
Chrome tabs would black out. Some pages, typically ones with Flash or some other multimedia content, would suddenly urn totally black. Sometimes when you opened the page again in a new tab, it would work, sometimes not. I think it had something to with nVidia drivers. The problem disappeared after upgrading the drivers and rebooting the computer.
nvidia-settings crashes when you try to apply settings. It still does, but it turns out that the Save to X Configuration File button actually works and you just need to restart the X server after making changes. No more hand-editing Xorg.conf.
Whenever I plug in my USB DAC (i.e. soundcard), I need to restart Spotify to hear audio again. It used to work without restarts, but maybe some software update broke it. (The said DAC, NuForce uDAC-2 occasionally overheats, so I unplug it when I leave the office.)
Sometimes, like every time I plug in a USB device, the X keyboard layout gets reset. I use xmodmap to set up a custom layout and this undoes all those customizations. My boss points out that instead of using xmodmap, I should create a proper XKB layout. I guess it would help, but I’ve never encountered this problem with xmodmap elsewhere.
