What should be done if everything in post #2 is set as directed, but on the following step...: glxgears -info |grep NVIDIA
...the following is returned?: X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 154 (GLX) Minor opcode of failed request: 3 (X_GLXCreateContext) Value in failed request: 0x0 Serial number of failed request: 31 Current serial number in output stream: 32 NOTE: The workaround provided in post #2 above did in fact solve this issue for a few months on my setup until this morning when this problem started happening again. My computers Specs: CPU: Two Intel(R) Xeon(R) CPU E5-2687W v3 @ 3.10GHz Mem: 64GB OS: Xubuntu 18.04.2 LTS Graphics: NVIDIA Quadro P6000 Software & Updates panel: [Ubuntu Software Tab]: (The following are checked) * Canonical-supported free and open-source software (main) * Community-maintained free and open-source software (universe) * Proprietary drivers for devices (restricted) * Software restricted by copyright or legal issues (multiverse) [Additional Drivers Tab]: (The following graphics driver is in use) * Using NVIDIA driver metapackage from nvidia-driver-390 (proprietary, tested) If I'm remembering correctly this setup is currently utalizing some of the functionality provided by the proprietary drivers that can not be provided by the more generic Noveau driver. I can't quite remember what this is at the moment but I would prefer to stick with the proprietary driver if at all possible while solving this problem. Please let me know if there are any other logs or information that I might be able to report in order to help verify or narrow down what is causing this issue to re-occur after the fix provided in step #2 has been applied.
