Since the upgrade from 16.04LTS to 18.04LTS I am struggling with an unstable machine.

*It takes ages to start (so slow I can compare it to old windows) *It randomly freezes to the point where I can only force shut it down and have to restart, obviously losing the work that wasn't saved. Interestigly the mouse work but all the rest of the desktop gets unresponsive completely.

Some details from Hardinfo:

Processor Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz Memory 16384MB (3208MB used) Machine Type Desktop Operating System Ubuntu 18.04 LTS Kernel Linux 4.15.0-20-generic (x86_64) Version #21-Ubuntu SMP Tue Apr 24 06:16:15 UTC 2018 C Library GNU C Library / (Ubuntu GLIBC 2.27-3ubuntu1) 2.27

I'd like to ask some help to understand what is the matter? Any log that could relatively easily show why it takes so long to start and why it crashes so many times a day?

  • Seem to have a similar problem. You running a graphics card? – BobserLuck May 16 '18 at 22:39
  • @BobserLuck indeed I have an nvidia graphics card. – NetNeutrality May 17 '18 at 21:00
  • I will try to get some evidence but I am starting to see a correlation with google chrome ie it seems whenever the OS freezes I am using chrome. Will revert to firefox and advise – NetNeutrality May 18 '18 at 22:50
  • I've used the machine for a few days on Firefox and the incidence of frozen desktop greatly reduced. Following the graphic card hint @BobserLuck I have now disabled the use hardware acceleration when available functionality on Chrome because I suspect that this setting could be at the root of this issue. – NetNeutrality Jun 4 '18 at 20:54
  • No joy after less than one hour using Chrome with disabled hardware acceleration when available functionality on the machine froze again. – NetNeutrality Jun 4 '18 at 22:31

Check whether you see the baloo-file process running - it is a search service that is indexing your files. In my case I had the same symptoms until after this search indexer completed. This should explain your improved experience over time as well.
