Intel Bay Trail Graphics

[InsideJob]

Now that I got my other issues I'm left with one glaring problem, OpenGL on my Pentium N3540. Apparently this used to be called an Atom CPU but Intel rebranded it. Also apparently, it used to be code-named Valley View Gen7 or something like that. Why the name changed I'm not sure, but under earlier versions of K/Ubuntu it still shows up that way.

This is what happens when I click OpenGL in KInfoCenter:

It locks up solid. At random times the application launcher also locks me up. I've cut back on desktop effects and that seems to help. 3D gaming is out out the question at this point. I was going to try kernel 4.1 but Canonical has yet to compile a stable version. Not looking for help at this point -- I'm pretty sure I've tried everything -- just noting it so others experiencing problems won't think it's them.

Here's my system info:

Try changing the compositing type from OpenGL 3.0 to OpenGL 2.0:

System Settings > Desktop Effects > Advanced > Compositing type

That's the default setting. The only other option is OpenGL 3.1 for some reason. My latest bleeding edge Intel driver says OpenGL 3.0 so I was afraid to even try that.

"unstable" shouldn't be interpreted literally. This kernel is straight from the source tree, with a few Ubuntu-specific patches added. It hasn't gone through extensive testing that you'd want for production servers, but it's sufficiently useful on desktop systems. Give it a try.

"unstable" shouldn't be interpreted literally.

I'm glad they're not being literal, because it looks like everything went to heck in a handbag around RC3.




In any case, the Intel DRM Next branch hasn't been updated since RC8 so I've got to wait for that version anyway.

The only obvious thing is that something changed between v4.1-rc2-vivid and v4.1-rc3-unstable. I doubt there's any "heck in a handbag"ery here at all -- more likely just a process change. I've asked for clarification: http://ubuntuforums.org/showthread.p...907&p=13310165

[InsideJob]

That's a lot of doubt and uncertainty. I was going to send Linus an email to let him know Canonical has declared all his release candidates less than stable (I don't want to be too literal), or maybe they're referring to his mental state, I dunno. Penguin attacks can leave long-lasting scars.

[SteveRiley]

Do you even know what "Debian unstable" is?

[InsideJob]

That sounds like a personal attack, please ban yourself in accordance with forum rules. Duh!

I know what heck in a handbag looks like:

They have a very lively discussion over there thanks to competent administration of their forums. I've never heard anyone called a troll for expressing a dissenting opinion.
