Pi2 falls back to software rendering

[multipitch]

Hi,

I'm running the latest supported alarm build and have the cinnamon DE installed.
When I log in, I get the popup message "Running in software rendering mode" and the display responsiveness is understandably terrible.
I tried an install with Gnome over the weekend and got similar results.

I'm installing X, the graphics drivers and cinnamon as follows, and I have the feeling I'm probably missing something obvious, but can't figure out where I'm going wrong:

Code: Select all

# pacman -S xorg-server xorg-server-utils xorg-xinit xf86-video-fbdev
# pacman -S cinnamon
$ echo 'exec cinnamon-session' > ~/.xinitrc
$ startx

Just because you are running "latest" does not mean some packages might need updating, why not use pacman -Syu?

I have neither cinnamon nor a pi2 but that is one thing that would need doing anyhow.

Also, did you google this? Did you try starting it with another DM and selecting "Cinnamon" rather than "Cinnamon (software rendering)"?

Hardware-acceleration for the RPi is still in development.
Note that Pi does support OpenGL ES acceleration
already , just not regular GLX / "desktop" OpenGL yet.

sjdif: Yes, I'm running a fully updated build.

ghans: I guess I'm not missing anything then, it's just not possible.
I assumed that since even my old 256 MB Pi can play HD video, the new Pi2 would have the graphics capabilities to run a full DE like cinnamon or gnome.
I'll try something lighter like enlightenment maybe.

Thanks

Don't forget LXDE, meant to be lightweight. I just run Openbox without LXDE, but people often run the two together. What I like about Openbox is being able to easily code keyboard mouse emulation.

You should run the DRM/KMS driver!
You will have to upport it from github.com/anholt/linux (I'm currently away from my Pi2, so I don't have the source tree)

Would it be possible (when you are back at your Pi2) to get some further information on how to compile and run this driver.

Thanks!

I used git bisect between the driver commits and the 3.18 kernel tree and added driver info to bcm2709

Tried lxde - works great!

Clearly there is a knowledge gap on my part here, is there an idiots guide to this.

I would also appreciate more information.

Would building the version here work? https://github.com/raspberrypi/linux

This is what arch builds it's kernel against, look at PKGBUILD, it's almost in script form

Good to know. I actually tried to compile the repo by hand following the instructions, but it wouldn't boot for some reason. Maybe I ended up with a armv6 instead of v7 or something.

Just been looking a bit more at the github.com/anholt/linux stuff. This seems relevant:
