I'm using Ubuntu 13.10, I've installed Unity tweak tool. Sometimes, when I maximize a window, the system freeze and I can't do anything (the system is still in freeze after 3 hours). I have to reboot my pc.
The last example was yesterday, when I've maximized Thunderbird by sliding the window to the top of my screen.
I don't know if this is relevant, but I'm using dual screen. I've tried to find an error in
/var/log/syslog
but I didn't find anything... Is there the right place to look ? Tell me if I need to add any info, I will be happy to do so !
EDIT 1:
To find error in syslog, I've done :
less /var/log/syslog.1 | grep error
I've also looked manually trough the last entries...
EDIT 2:
After playing a bit with multiples softwares, it looks like the crash only appears when using Thunderbird ! Have you had similar experience with Thunderbird ?
EDIT 3:
I should have say it from the beginning, but it only happens when I resize a windows by pulling it on the edge of the screen !
