This occurs in different scenarios. Here's one: Thunar devices list shows attached but unmounted external drive B. The drive is encrypted. In normal practice the following works as expected: mouse click drive B in Thunar devices list; Thunar gives popus asking for encryption password; password entered; Thunar accepts; drive mounts and opens in Thunar browser view.
However, >cancel< the password form before entering the password and the following happens: - drive B in Thunar drive list shows a progress dial, that turns perpetually - Thunar process consumes about 15 per cent processing power perpetually Thunar doesn't want to let go. Click it again, you can enter the password and it opens okay. But it essentially gives you no choice option but to click again and enter the password. If you don't then Thunar will just sit there tapping its foot, hogging your processor. (Now as an aside here, there is an inconsistency that is a related but perhaps separate bug that is nevertheless worth mentioning. That is that if a drive is connected but not mounted, Thunar shows it so as a greyed- out entry in its drives list. But if, after you have mounted the drive, you use Thunar to dismount it (using, e.g. the Thunar >eject< buttton), the drive disappears from the list completely, meaning you have to intervene physically if you want to mount it again). Here's another scenario, recounted slightly flakily from notes, but this is a good enough account to give some help in diagnosing the problem: This error occured in a similar scenario the other day - another external USB disk that had been auto-dismounted on the count of midnight, also encyrpted. So the Thunar progress wheel is turning perpetually, using about 50 per cent processor time. I dismounted it from Thunar, but it stayed there in the devices list. I clicked on drive in Thunar devices list again. It disappeared from the list, and Thunar said: "device not found". But the drive was still mounted because quodlibet music player was using it. I closed all apps using the device and tried to dismount it from the command line, but system said I couldn't because the drive was busy. Another backup icon appeared in the devices list when I wasn't looking. I ejected it successfully this time and that was that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1223848 Title: Thunar hogging processor after problem mounting external drive To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunar/+bug/1223848/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
