Comment 35 for bug 1389904

My problem with my i810 seems to be the same and the crude fix of reinstalling the old version through sudo apt-get install xserver-xorg-video-intel=2:2.99.910-0ubuntu1 and pinning it with sudo apt-mark hold xserver-xorg-video-intel=2:2.99.910-0ubuntu1 is working.

Let me tell you some background and guesswork why we have this problem. Because I haven't taken notes and the i810 computer is not at hands I might sound a bit fuzzy...

X11 itself is not enough for modern video output. You also need DRI, GLX, MESA and others which are usually seperate from X11 and X11 low level drivers but are still pretty low level themselves. Starting with Ubuntu 14.04 the official DRI/GLX-drivers no longer support i810 (maybe this problem is older but 12.04 definitly does not have the problem, not sure if GLX or DRI, either libgl1-mesa-dri or libgl1-mesa-glx) . This in return means you get no MESA/OpenGL and no accelerated video. This is an Upstream-Decision outside Ubuntu and I was unable to find any explanaition for this though it was hinted that a lack for DRI/GLX means that i810 support itself might not live for much longer in Xorg.

So I guess now is the time where i810 not only loses OpenGL and accelerated video upstream but is completely dropped from Xorg. Things look hopeless, already when i810-GLX/DRI got dropped upstream sounded totally uninterested in fixing it. Basically they suggested to compile your drivers manually based on older sources. And they sounded absolutely final on not fixing GLX/DRI.

This is a real pitty because I have several of these old, quiet, small computers with i810 around and they worked perfectly good with 10.04. I can only hope someone has the time to do a PPA with working DRI/GLX/Xorg-Intel810.
