Je viens d'installer xubuntu 20.04 sur un vieux pc pour mon fils, et au lancement du jeux warzone2100 le message suivant s'affiche "openGL 2.0 not surpported! upgrade your drivers"
j'ai fait
glxinfo | grep 'version'
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
Max core profile version: 0.0
Max compat profile version: 1.4
Max GLES1 profile version: 1.1
Max GLES[23] profile version: 2.0
OpenGL version string: 1.4 Mesa 20.0.8
OpenGL ES profile version string: OpenGL ES 2.0 Mesa 20.0.8
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16
puis j'ai tenté
sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt-get update
sudo apt-get dist-upgrade
OpenGL était toujours en version 1.4
Après un
sudo apt-get install ppa-purge
sudo ppa-purge ppa:oibaf/graphics-drivers
j'ai testé avec
sudo add-apt-repository ppa:xorg-edgers/ppa

== Important notice ==
This PPA is currently meant to be used as a whole. Please do _not_ individually install packages from it, add it to your sources and let your package manager pull in every update. The packages here build against each other and compile different features based on whats available at build time. Do not assume that because it lets you install a DDX with just the driver and libdrm update that it will work. These packages are made with scripts that use the the current packages as the base, so some dependencies can be wrong and your package manager will not resolve that for you. If you want to individually install something from here, grab the source and rebuild it in your current environment instead.
** Please do not publish instructions for how to install from this archive without linking to this page! Anyone using packages from this archive is expected to read this page first and it is recommended to check back occasionally for notice on problems that may arise. **
** Please use ppa-purge to remove this PPA. It is *particularly* recommended to do this before upgrading to a new ubuntu release! **

Le PC étant vieux (<2010) peut-être tout simplement que la puce n'est pas compatible? J'ai cherché mais n'ai rien trouvé comme info (il semble que la puce soit (intel corporation 82945g/gz integrated graphics controller (rev 02) prog-if 00 [VGA controller]).
Un tuyau?
