[Nouveau] Problems with nouveau driver in Ubuntu 18.04

Thu Feb 27 10:03:27 UTC 2020

Hello,

I use Ubuntu 18.04, since one of the last upgrades I have problems with nouveau drivers.

My screen look like the picture atteched.

 [~]$ uname -a
Linux  5.3.0-40-generic #32~18.04.1-Ubuntu SMP Mon Feb 3 14:05:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

[~]$ inxi -Gx
Graphics:  Card: NVIDIA G71GL [Quadro FX 1500] bus-ID: 01:00.0
           Display Server: x11 (X.Org 1.20.5 ) driver: nouveau Resolution: 1920x1080 at 60.00hz<mailto:1920x1080 at 60.00hz>, 1920x1080 at 60.00hz<mailto:1920x1080 at 60.00hz>
           OpenGL: renderer: NV49 version: 2.1 Mesa 19.2.8 Direct Render: Yes

I have tried to install Nvidia driver 304.137, but it seems is not supported in Ubuntu 18.04 anymore.

Are there any nouveau upgrade (that it is not on Canonical) that fixes this problem?

Or how I can downgrade nouveau driver to any previous one that works fine in ubuntu 18.04 with my graphics card?

Regards!

Juanma
