My Ubuntu laptop had an update which I attempted to run. I didn't close out of Boinc prior to running the update, but I think the update went through. However, Boinc Manager didn't seem to be responsive during/after the update. I ended up restarting the computer, and since then I can click on boinc manager, but it never opens. I've restarted a couple of times to be sure, but the problem still persists.

I'm a Linux noob. I know I'm running Ubuntu 18.04 and Boinc 7.14.2, but I'm stuck with how to un-stuck the manager. Any thoughts?

First check the task bar. If somewhere to the right of it is a BOINC icon, it is running in the back ground. Double click on it and it should bring up the manager to your screen.

To check whether the client is running open a terminal and type, "top" followed by enter. The line on the screen that will tell you if the client is running is at the bottom.

Okay, now I'm not sure what's going on. I brought the laptop to work today to diagnose when I had a free moment. Earlier today I tried booting it up, and it wouldn't even get to the GUI. I turned off the laptop, and a few hours tried again and now it boots up and boinc manager loads up! I then turned it off, turned it back on again, and it is flashing the Ubuntu screen as the "dots" change between white and orange. I think Ubuntu didn't update properly and something is screwy. I'm going to attempt to reinstall it when I get home. Thanks for the help, Dave, but I'm thinking my problems are bigger than Boinc at this moment.

If re-installing from scratch, I would go for 19.04 No problems with it so far.

Just disregard this thread altogether. I got home last night, turned on the laptop, and after a long boot it finally got up and running. I think I got impatient because I saw no HDD activity for several minutes and it caused this whole mess.

Linux can take an age to boot after updates and filed boots....
In the past I've found the reciting the incantation "If you don't behave yourself you stupid lump of silicone I'll blow Linux away and install Windows CE" loudly and repeated a dozen times has worked ;-)

If CE isn't enough add 2 more Windows OS versions. CE-ME-NT
