[Kernel-packages] [Bug 1731968] Re: 384.90-0ubuntu0.16.04.2 EGL crashes at startup
This works when installing using the runfile method, but fails for the packaged drivers. So it definitely appears to be a packaging issue specific to Ubuntu. Confirmed to work on Fedora and Arch with 390-series drivers as well. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-390 in Ubuntu. https://bugs.launchpad.net/bugs/1731968 Title: 384.90-0ubuntu0.16.04.2 EGL crashes at startup Status in nvidia-graphics-drivers package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-384 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-390 package in Ubuntu: Confirmed Bug description: Release: Ubuntu 16.04.3 LTS Package version: 384.90-0ubuntu0.16.04.2 In the latest driver 384.90-0ubuntu0.16.04.2, EGL initialisation is now broken and the GL context returned is inconsistent leading to crashes.

This is still a problem in 396.45 on Ubuntu 16.04. The minimal test case fails, and EGL doesn't work cleanly. Tested on clean installation with an Nvidia Titan Xp and Titan X (Pascal). ** Also affects: nvidia-graphics-drivers-390 (Ubuntu) Importance: Undecided Status: New ** Also affects: nvidia-graphics-drivers (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-390 in Ubuntu. https://bugs.launchpad.net/bugs/1731968 Title: 384.90-0ubuntu0.16.04.2 EGL crashes at startup Status in nvidia-graphics-drivers package in Ubuntu: New Status in nvidia-graphics-drivers-384 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-390 package in Ubuntu: New Bug description: Release: Ubuntu 16.04.3 LTS Package version: 384.90-0ubuntu0.16.04.2 In the latest driver 384.90-0ubuntu0.16.04.2, EGL initialisation is now broken and the GL context returned is inconsistent leading to crashes.
