Acer Chromebook CB5-311 mainline

@reey
Thanks for link to your defconfig file, really useful. Managed to use your defconfig to work out what's wrong with mine. Still have issues but udev and the backlight is now working. It's better using a defconfig than copying the .config from a previous release.

Still issues to resolve but 5.1 working well.

1080p playback with ffplay/ffmpeg is ok for me as it plays back with good timing with audio in sync. I'm just not sure its as smooth as should be. Watching stuff in firefox is not 100% smooth like on google chrome. changing the pstate does not improve accelerated graphics. The nouveau stuff is working but can not match the performance of nvidia drivers used in chromeos. I really recommend creating a config from reey's defconfig mentioned to on the previous page. I couldn't use it on fedora as it lacks the stuff for audit, selinux and firewalld but was able use it to improve my config. I'm sure it works really well on arch, have not tried it yet though.

Although I generally like the acer we have, I will try and avoid anything nvidia based in the future. It looked promising when the nyan based chromebooks were launched but Nvidia seem only really focused on the other tegra boards. As of September when Google drop the support for the cb5-311 we're on our own. I'm planning on flashing the spi before this date but still use chromeos to watch films etc.

Thanks for your quick reply, @fedup! This motivated me to try and fix my video issue - but without success so far. Switching to reey's kernel config did not help. That came at not much of a surprise, since my kernel config was based on his anyway, without a lot of modifications.

But I found out my Xorg is not actually using the nouveau driver! I wonder what is going on there?

Initially I did not even have extra/xf86-video-nouveau, but that is fixed now. I also uninstalled extra/xf86-video-fbdev, which lead to different log messages, but still no nouveau driver being loaded. I even tried to make my system load nouveau manually, but that did not work either:
$this->bbcode_second_pass_code('', '
Section "Device"
Identifier "NvidiaGraphics"
Driver "Nouveau"
EndSection
')

This make nouveau load, but it quits immediately with some not very helpful error message in the log file.

I'm afraid I might have to install a fresh system? But I don't know how to best do that now, I don't have the time, and that's not the Linux way...

Hi all, finally updated arch again.

@reey thanks for the kernel builds on your github releases, very helpful.

Observations:

systemctl suspend still freezes the system before it can suspend, so one of the most important functions of an ultra mobile laptop still doesn't work...

Xorg has super high CPU usage when doing anything but idle - dragging windows, doing anything in firefox.... desktop compositing still has to be used to make dragging windows in xorg not super slow.

Still no dynamic reclocking, still the lowest clock as default. Use something like pstate 6 for a sligthly less crappy experience:
sudo bash -c "echo 06 > /sys/kernel/debug/dri/128/pstate"
sudo bash -c "echo 06 > /sys/kernel/debug/dri/129/pstate"
128 or 129 depends on which gpu chip gets initialized first.

gnome-session --session gnome-wayland crashes immediately, weston freezes very shortly after launch. Seems we are stuck with Xorg?

Even in an empty Xorg session, kwin crashes very easily in libdrm nouveau when dragging a single xterm window around. Sad to see that nouveau is still so unstable. I'm using XFCE for now...

The glxgears window is empty, but other OpenGL stuff seems to work.

@vman
xf86-video-nouveau can not be used because the nvidia GPU is not actually connected to the display output. There is a "dumb GPU" connected to the display that can not really do acceleration, and all rendering has to be offloaded to the nvidia GPU in the background. The mesa "tegra" driver does offloading to the mesa nouveau driver fully automatically, if you see something like OpenGL renderer string: tegra in the output of glxinfo | grep OpenGL, because the "tegra" mesa driver is just a fake driver that unifies the dumb display chip and the nvidia GPU and pretends to be a single GPU.

fbdev from xf86-video-fbdev and the X server's inbuilt modesetting ddx which is used when uninstalling fbdev seem to run equally crappy on the tegra display chip. I don't know if there is a way to get 2D a little bit faster and to have it use less CPU, but it would *really* help.

Hi everyone,

with the end of official support for our device I thought it would be the right moment to post a _simple_ and up-to-date way of installing proper Linux on it... and I'm really somewhat annoyed by the bad performance I'm getting out of it right now. I even started looking at the new PineBookPro... but although that's never it might even be inferior in some aspects (3D graphics, sound?).

My last posting was reflecting my frustration, especially with not being able to take as much time as I apparently need to figure out a working solution. Maybe I made a little progress, though, and one of you guys can help me getting this "GLAMOR Textured Video" setup running, so I can see for myself if it is good enough for my purposes?

I compiled U-Boot from reey's Arch package, and dd copied it to the first partition of a GPT partitioned SD card, pretty much as described in the NetBSD tutorial I mentioned before. Then I created a second partition with cfdisk, formatting it with ext4. I tried installing three different distributions on it, with varying, limited success:

• Debian 10 only gave me the familiar blank screen when trying to boot. I may have made a mistake when copying the kernel and dtbs, because then I was still using a separate /boot partition. I'm tempted to just try this again. The blank screen seems to be the consequence of not finding all required files on the partition indicated in the "root=" kernel parameter. I tried a 5.0 kernel with LPAE.
• Arch would boot ok, but I did not get a graphical setup configured. sddm never started. A direct call of weston-launch is showing a nice looking desktop, but input freezes after no more than a second.
• Ubuntu 19.04 (with a 5.0 kernel) only shows bad screen corruption when loading the Kernel from U-Boot.

So I'm wondering, if you have "something" in xvinfo: which distribution did you install? Which kernel? How do you launch your graphical environment? Do you have any magic in your extlinux.conf?

Hi everyone,
I don't know if this topic is the right one for my question but I've searched for long time and I don't know how to fix my black/blank screen issue. I have new installation of Arch and when I log in for the first time everything is fine, bu when I reboot/log off/turn off from Arch and try again to log in I see only black screen. I've tried to install Arch again but there is the same thing. Do you have any ideas how to fix or check this issue? Of course I have CB5-311 and Arch ARM ver.

[vman]

Hi @PopS,

to be able to help you I think I need a little more detail. Most importantly: how much do you see after you turn on the device? The initial white "debug" screen appears, I assume? Then you're trying to boot from the internal mmcblk0 (ctrl+d), or from an sd card (ctrl+u)? Did this work once at all (immediately after the installation)? Is the screen going blank there, or do you see kernel messages, and even get a login screen?
If you think your system might be booting, you could try to attach a usb-ethernet adapter, and log in with ssh, from a different machine, to better be able to investigate what's going wrong.
Today I actually had one instance of my cb5-311 not booting up properly, and just showing a blank screen. Resetting it by pushing a twisted paper-clip into the little hole a the bottom, I could boot properly on the second attempt. I'm still booting Arch with the Kernel being written to a "Chrome OS kernel" partition on an SD card (/dev/mmcblk2). My attempts with U-Boot where not that successful, as described in my last post, just before yours.

Hi @vman
to be more specific: After fresh install of Arch I am able to boot properly - I see login menu, I can log in, install apps and the all the stuff. The problem starts when I log off or restart device - I'm not able to log in on the same account but I can log in to "fresh" (not used even once) account if I have made new accounts on the first time being logged in. I've made investigation for this and it's problem with graphic drivers - I have removed them from Arch and now I'm able to log in multiple times but the sys behaviour is really bad (much laggy) - so I'm trying to figure out which option is better to deal with.

The idea with SSH is really good I will try it in next few days and we will see if I'm able to fix this issues.

I'm working with SD card version too and basically I don't have problem with getting into log in screen in Arch (the problem is later as I mentioned above).

[vman]

Hi PopS,

it's a good thing your system is booting properly at least. I lost count of how many times I sat there just staring at a blank screen (before the login screen would come up). If you get to the login screen all right you have another option, easier than ssh: just try ctrl+alt+F1 to change to a different terminal, and try to login there, completely without a desktop environment. You could also try a different desktop environment. I'm mostly using KDE, which is quite laggy with my graphics setup, but in the past I had a better experience with XFCE.

You can also try switching login managers. I'm on sddm now, but e.g. lightdm should also work.

So when you have a graphical login, what's the output of xvinfo? If it is "GLAMOR Textured Video" instead of "no adaptors present" I'd be very interested in how you got there!

Edit: And you can increase you video chip clock for a better desktop experience. See this post:
