Updated and Optimized Ubuntu Free Graphics Drivers

[oibaf]

Ubuntu 15.04/vivid will EOL tomorrow make sure to upgrade to wily ASAP. Suggested path is to purge the PPA, upgrade to wily, add again the PPA.

Running upgrade.sh will automatically replace the -lts-vivid versions with standard named ones, such as xserver-xorg-core, and so forth. There will then be no need to run dist-upgrade, you can just run apt-get upgrade to bring in the latest from Oibaf's PPA (other than the xserver-org-video-* packages, because of my new xserver-xorg-core version, which has an incompatible ABI - it changed from 1.17.X to 1.18.0). The only package brought in should be mesa, which gets built twice a day at 07.30 and 19.30, until Oibaf updates libva and the vaapi-intel-driver with the latest from git.

As for whose fault it is with the -lts-vivid packages, it's definitely not Oibaf's fault. Mint possibly could have stayed with the X.org and packages from trusty, but I can understand their wanting to have the latest. The one thing I am not totally sure on is why Ubuntu went with this naming convention - presumably because they had done so before, with -lts-utopic - but it makes upgrading a total pain. Basically you have to modify the Debian control files and remove all conflicts, then everything will play nice.

I have also created a cairo subfolder, it's not included in the upgrade.sh script as it's optional, but if you do want the latest cairo (1.14.6) from Xenial after upgrading the stack, simply run

sudo dpkg --force-overwrite -i *.deb

in that folder.

I uploaded llvm 3.8 and rebuilt mesa and libclc with it.

Having a problem running PCSX2 with the Oibaf PPA. Have two machines, one with Oibaf PPA and one with whatever came with Mint 17.3. The Mint 17.3 without Oibaf PPA has no problem running PCSX2. Mint with Oibaf PPA gives this output error.

Are those graphic features really not supported?

With 17.3, you can now add ppa:tigerite/mint-xorg-update and simply run

apt-get update
apt-get upgrade
apt-get install xorg-update

After that, you can enable the Oibaf PPA for newer versions of everything except the xorg-server-video-* files. I'll keep those up-to-date as much as possible (they are currently in-sync).

If any packages get held back, other than xorg-server-video- ones, you should be able to apt-get install them separately (such as cups and dpkg). I don't know why it doesn't bring them in automatically, they're not broken packages.

WoW, thanks Tigerite. That will certainly make things easier. I'll test it and report what happens.

Hello!
On Fedora 23 (test update xorg-x11-drv-intel-2.99.917-19.20151206.fc23 ) by default was enabled DRI3. Will be enabled DRI3 on the Ubuntu ppaoibaf ? Video driver Intel HD 4600.

[Tigerite]

I've changed the default to DRI3 in my PPA, but I don't think it makes much difference; the i965 driver still uses DRI2:

You can check what DRI is used by running "LIBGL_DEBUG=verbose glxgears" (string "libGL: Using DRI3 for screen 0").

Hi oibaf!

First i want say thanks for the drivers, i have +20-25FPS, so this is better a lot than OS X/Windows. I have found a problem, and it looks like driver bug. When i boot the laptop, the Gnome shell crashes after 5-10 minutes, after this, it works without problems for days. Here is the log: http://pastebin.com/sg8zNV5Z

And my other question: How to check that the drivers are installed correctly? glxinfo | grep OpenGL:

Edit: Can i change the frequency up/down threshold for GPU usage? When i play, the GPU downclocks itself, the cooling is good. In OSX i can configure that, 50% GPU usage = 1100Mhz, 40% usage = the frequency slowly steps down to 650Mhz. Is this possible on Linux?

Thanks for reply.
