Cinnamon in software rendering mode LMDE, Intel i7-7560U

Postby petewt » Mon Jun 19, 2017 12:18 am

Hi,

Working on a Dell XPS13 Developer Edition which came with Ubuntu 16.04LTS installed. Made some tweaks to secure boot in bios and I have a functioning LMDE install except for that Cinnamon runs in software rendering mode. I reviewed some other posts with similar issues but not on Debian version. Any assistance would be much appreciated.

You probably need a newer kernel. Linux kernel 4.10 or 4.11 is best for systems with Kaby Lake. I don't know what the recommended way is to get it on Debian 8 (the current LMDE 2 package base; though mind that even Debian 9 currently only has 4.9). Hopefully somebody else can help with that.

Thanks!

Linux kernel 4.10 or 4.11 is best for systems with Kaby Lake.


I suspected as much and spent some time trying to figure out how to upgrade the kernel without any luck. Would appreciate any additional guidance upgrading Debian 8 kernel to 4.10 or 4.11 if that even possible...

I think that it's possible to get Kaby Lake working correctly even on a 4.9 kernel. Have you updated the firmware-misc-nonfree package from the jessie-backports repo? Kabylake graphics need some non-free firmware to work correctly in Debian or derivatives. You probably also want the latest intel-microcode you can find in jessie-backports or upstream Debian.

I have an OBS repo with up to 4.11 Liquorix kernels backported to Debian, but the 4.11 kernel is acting unstable on my Skylake laptop, so I'd go for the 4.10 one in there.

https://software.opensuse.org//download ... e=codelite

Run all the install commands as root, except you should run the wget command to download the repo key as a standard user. I believe that you can also use sudo instead of root. Make sure to keep your 4.9 kernel as a backup boot option until you are convinced that the 4.10 is working well enough. I also have some proprietary drivers in that repo patched to build with newer kernels, plus an even newer non-free firmware set of packages lifted from SteamOS:

https://build.opensuse.org/project/show ... r:codelite

However, just installing a newer kernel and driver is not enough to get full hardware acceleration: http://forums.debian.net/viewtopic.php?f=16&t=131611

I've set up jessie backports and installed the recommended packages with no luck. It seems that 4.10 is not available:

I'm not sure I understand how the OBS repo works. It looks like its setup to install codelite? Does that come with 4.1X kernel?

OK, I've now successfully installed the 4.11.6 kernel and still having the 'Running in software rendering mode` error. I love Mint Debian. I don't want to use Ubuntu....But I am getting to the end of my known universe. Any other suggestions welcome. Is there something I need to do with BIOS? Secure boot is disabled...

Thanks in advance.

Did you also apply the other updates from jessie-backports in that HowTo? What does

Code: Select all

inxi -G


and

Code: Select all

apt-cache policy firmware-misc-nonfree


and make sure you are running the new kernel with

Code: Select all

uname -a


About codelite: the OBS has some odd quirks that I have to work around. One is that it generates the automatic install instructions for a repo based on the name of one of the finished packages in it, and the Liquorix kernel packages are all architecture dependent, having names with "amd64" or "i386" in them. I needed one that was the same no matter what platform, so I added the kernel to a codelite repo I already had set up. As long as I have one package I can use to get the instructions, all others in that repo can use those instructions. Codelite won't be installed automatically, but it will be seen as an upgrade if you have the Jessie version installed.

Hi!

Thanks very much for this. I've upgraded to the most recent kernel and still having the software rendering issue. Would the codelite repo add anything that I would not have gotten with the 4.11 kernel?

One poster in that Debian thread said he also had to upgrade libdrm-intel1 and libgbm1 from jessie-backports to get full acceleration, so check what version of those you have, and then try the upgrade if you don't have them. I'm assuming you are rebooting after the upgrades, also...
