Did you try to compile the mesa version in which it did work and replace the system one and put the packages on hold. The drivers may not work nicely on newer mesa even if you drag them into a newer mesa. <div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">El lun, 10 de feb. de 2025 12:40, Jeff Berry <<a href="mailto:Jeff.Berry@mrc-cbu.cam.ac.uk">Jeff.Berry@mrc-cbu.cam.ac.uk</a>> escribió: </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div lang="EN-GB" link="#0563C1" vlink="#954F72"> <div class="m_-3340884283438993458WordSection1"> Good afternoon, I'm hoping this is a good place to seek some guidance. We've got a set of Dell rack servers that we run headless. We'd been using CentOS 7 and were able to get OpenGL running via vnc or x2go. We are upgrading our cluster to Ubuntu 24, and now the OpenGL is not running. After running around in circles and chasing down various leads, I suspect the problem is that mesa no longer supports the Matrox cards which the Dell racks are using. (If someone has a better idea, I'd love to hear it!) I can get OpenGL sort of working if I stick a bunch of old GL and Mesa libs in a directory and set that up using LD_LIBRARY_PATH, but that's not ideal. (And doesn't really work very well.) The docs (<a href="https://docs.mesa3d.org/systems.html" target="_blank" rel="noreferrer">https://docs.mesa3d.org/systems.html</a>) say that Matrox is deprecated but ' If anyone’s interested though, the code can be found in the Git repo.' My questions are roughly: 1) am I off base in thinking this is probably the issue? a) if so, what else should I be looking at? 2) has anyone had a similar issue and tried to get the Matrox drivers built for later versions of Mesa a) if so, any pointers? 3) more generally, are there pointers or docs on where to get the code and how to integrate it? git is not something I use much, and although I had poke at it, I've not got a good idea of where to get the code. Hoping that someone can point me in the right direction ... Kind regards, Jeff Berry, MRC Cognition and Brain Sciences Unit </div> </div> </blockquote></div>
