It happens when I just type sudo startxfce4

[sparrino]

Yeah, this just started for me too. There was an update a few days ago, I know because the chromebook had "Restart and Apply Updates" in place of "Sign Out" in the menu. Ever since then, I have been getting the same problems as the above person when they enter the chroot. I am running precise and xfce, I'll try running unity and lxde, and if it works I'll let you know, but I do not have high hopes.

Already updated crouton (sudo sh ~/Downloads/crouton -u) and even reinstalled it on another chromebook but no dice.

It must be the latest update, I really hate those things ;)
Hopefully a fix will come soon,
Thanks!

[sparrino]

Well, as an update to my earlier post. I can't believe it, but I can start AND use LXDE normally. XFCE and Unity are not functioning normally but LXDE is working fine, at least on my chromebook.

You can install LXDE even if you already have Unity installed by going to CROSH and typing:

sudo sh -e ~/Downloads/crouton -t lxde -u

then after installation you can run it by typing

sudo startlxde

I use crouton to run the Arduino IDE on chromebooks for about 20 high school students, so it looks like I have a lot of chromebooks to reconfigure. ;D

enjoy,

Doc P

@sparrino
Thanks for this info! I dislike lxde so I don't want to do use that. The three that I would want to use is xfce, KDE, and unity. So I might have to test if KDE works.

[hinnefe2]

I had this same issue (something about SELinux and DBus was broken by a recent ChromeOS update) and updating the chroot fixed the issue for me.

Specifically, I ran

• croutonversion -u -d -c from within the chroot, then
• sudo sh ~/Downloads/crouton -u -n chrootname from outside the chroot. After doing that startxfce4 works again.

[Trimbell]

Well, I did what @hinnefe2 suggested but unfortunately I am getting the exact same errors. Any other suggestions?

[sparrino]

@hinnefe2

I bet your problem being fixed has to do with the fact that you are running trusty, I have the earlier release (precise, 12.04) and updating hasn't changed a thing: the only thing that remains functional (somewhat) is lxde :(

Any idea when a fix will come? Is someone still actively developing crouton? Thanks!

[wesleytsang]

I have the same issue. Please let me know if you guys find the solution.

[jbgross]

I'm having the same problem with my Toshiba Chromebook 2 2015 model. I powerwashed and tried building a new chroot from scratch and nothing worked. I couldn't add the file as recommended in this thread https://github.com/dnschneid/crouton/issues/2843, as I got a read-only filesystem error (with sudo).

I had a problem with trusty (I can't remember what), and I'm on the road and don't have time to mess with an upgrade, so I'm using LXDE.
@wesleytsang are you able to run LXDE? If so, is that not sufficient? Have you tried Pixel?

[brundizzle]

same issues here (acer CB15) ... even LXDE not running here :(

[brundizzle]

Problem solved with this thread:
https://github.com/dnschneid/crouton/issues/2926

[jbgross]

@brundizzle am I correct in assuming you have lxde working, but not xfce? If you got xfce working, was it just adding the file from the KDE/Minecraft guy in the other thread?

[brundizzle]

@jbgross nope... neither worked for me.
but the solution was as described by the guy mentioning minecraft. (i actually didn't have to add the file because it was already there. . i just had to edit it) . . . editing can be a bit tricky because you are in a shell. . . . full proces of what i did (hope i recall well :) :

1) ctrl-alt-t
2) shell
3) sudo enter-chroot -n
4) cd
5) sudo vi . . . ok, i didnt know how else to edit the file, so i used vi. . if you r not familiair with vi, you are going to get stuck here. . . so you either google the vi editor first, or yoy find another way to edit files in shell mode. . I made sure the [Option "AccelMethod"] was set to "uxa" (see other thread) . . . i think the guy copied/overwrote the file because the other file had the parameter set to "uxa" already .

6) exit
7) sudo startfxce4

and it worked !

good luck!

I'm pretty sure the OPs 'precise' selinux/dbus errors are different than the blackscreen errors that https://github.com/dnschneid/crouton/issues/2926#issuecomment-269165182 addresses.

That said, I don't think there are currently any fixes for the 'precise' selinux/dbus errors other than upgrading or installing a newer release. I have been using 'trusty', which is supported, and 'xenial' successfully but both may be experiencing the 'blackscreen issue' at the moment.

Hope this helps,

[Yerffy]

@sparrino Very happy that I can at the very least, have linux on my chromebook, I'm just super upset xfce does not work, thank you for the help though! 🥇

[DennisLfromGA]

@Yerffy,

xfce4 should work on releases newer than 'precise', with a little work that is...

Hope this helps,
-DennisL

[jcvernaleo]

xfce4 works great on trusty (on an Asus C201) for me. At least until I get around to making spectrwm or fvwm work that is :)

[jbgross]

Yes, this appears to be an entirely different problem; in my case, there is
no blank screen because the WM does not even start.
