My system updated the long lived branch Nvidia drivers to 375.39 yesterday. The problem is that now, when the computer goes to sleep, then wakes up, some windows are buggy:
The same happens with terminal windows. I tried the short lived branch latest drivers, the 378.13, it is the same problem. What can I do ?
Update: Now the drivers 375.39 are the official Nvidia drivers available from the Ubuntu repository, yet the bug evoked above is still there.
I have also reported the same issue to Ubuntu nvidia-graphics-drivers-375 package in launchpad. The workaround I found was to click an effect button in CompizConfig Setting Manager --> Effects.
I also described another issue for this driver and a temporary work around here.
For those affected, please help to add your voice to the launchpad bug report.
Update: I have shared a better temporary solution in that bug report that removes the bad window borders every time the computer wakes from suspend mode. See comment 13. Pending NVidia to provide a more permanent fix.
Update2: Pls also see comment 44. This workaround is suitable if you are using Ubuntu 16.04.2 LTS with kernel 4.8.0-xx instead of kernel 4.4.0.xx.
Update3 (8th Apr 2017): The new 381.09 beta driver with the bug fix is now available. Use 381.09 driver instead of 375.39 or 378.13. See comments #54 & #55.
Update4 (1st June 2017): The new 375.66 driver was released on 4th May 2017 with fixes to resolve many of the bugs related to 375.39. I have used it since it was made available by "Graphics Driver" team ppa and I have not encountered any issues, works great with 16.04.2. Use driver 375.66 as it is the latest long-lived branch release, else use driver 381.22(which takes over 381.09).
Not really a perfect fix as it doesn't solve the issue but, to recover after the driver glitches upon waking from sleep you can open a new terminal and just relaunch unity via...
blahblah@Computer:~$unity
Some programs don't always recover nicely (eg: chrome will have to be relaunched), but its a bit faster than restarting or logging out / in.
The 375 and 378 drivers are installed from an unoffical repository and are not proven to be working with Ubuntu without any issues.
You can remove the drivers by
sudo apt install ppa-purge
sudo ppa-purge ppa:graphics-drivers/ppa
sudo apt update
sudo apt install nvidia-367
This will install the officially provided Nvidia drivers.
This issue is present in 375 and 378 drivers...
Given that simply killing compiz process fixes the bad border problem, I have tested a solution that works on my Ubuntu 16.04 system every time after the system wakes.
I created a script called fixbadborders in the directory /lib/systemd/system-sleep.
It contained the following:
#!/bin/sh
## This file (or a link to it) must be in the folder /lib/systemd/system-sleep/
## Purpose: Kill compiz after system wakes up from sleep.
## This will fix bad window borders caused by Nvidia driver 375.39.
kill $(ps -C compiz -o pid=)
Allowed the script to have execute permission with:
sudo chmod +x fixbadborders
To remove this script:
sudo rm /lib/systemd/system-sleep/fixbadborders
