Please describe your issue:

updated chrome OS now chroots won’t boot to gui, something to do with dbus failing?

haven’t checked the CLI only chroot.

If known, describe the steps to reproduce the issue:

I noticed that the xf86-video-intel driver was being referenced in startlxde. According to some arch posts modeset should be used over xf86-video-intel, SNA acceleration sometimes causes problems and UXA can solve some issues.

The file I chaged was /usr/share/X11/xorg.conf.d/20-crouton-intel-sna.conf:

Section "Device"                                                                                                                                     
#   Identifier "Intel Graphics SNA+TearFree"                                                                         
#   Option     "AccelMethod" "sna"                                                                                                                   
#   Option     "TearFree"    "true"                                                                                                        
   Identifier "Modesetting"                                                                                                                
   Driver     "modesetting"
   Option "AccelMethod" "sna"
   Option "TearFree" "true"                                                                                                                  
EndSection   

Im not sure about the performance comparisons, however i am trying this for now since it seems to be working.

Edit 1: The issue i was having was that crouton booted but i got what looked like an unlit black screen.

Edit 2: @DennisLfromGA thanks for clarifying this issue. I agree that this probably does nothing for the dbus error.

Edit 3: The xf86EnableIOPort error discussion moved to #2926. New parameters added to the original posting in order to avoid confusion.

Output of startlxde before proposed fix. This output was actually run after I moved to the dev channel, moving to the dev channel is not part of the proposed work around.

I think the xorg conf file should be like this if you want acceleration with modesetting driver:

Section "Device"
   Identifier "Modesetting"
   Driver     "modesetting"
   Option     "AccelMethod" "glamor"
   Option     "PageFlip"    "true"
EndSection

At least according to manual pages valid choices for “AccelMethod” are “glamor” and “none”. This works for me for both trusty and xenial xfce4 chroot with 56.x ChromeOS on c720 (Celeron 2955U). Desktop that is, I haven’t tested any applications that would really require acceleration. I made accidental ChromeOS update yesterday and here are my experiences with modesetting driver so far:

Trusty:

  • There appears to be tearing. “PageFlip” option should help, but does not seem to.
  • Windows in Firefox are not always rendered when content of window changes.
  • Sometimes when starting chroot I get black screen with cursor. Switching to ChromeOS and back fixes this.

Xenial:

  • No tearing, no rendering problems. Seems to just work.

I am using xenial graphics stack on trusty, but it provides 1.18.3 xorg-core and xenial has 1.18.4. Maybe that explains differences in tearing and rendering.

vim filename

vim is a text editor. Google how to use it first. Trust me on that.

@eliot2 https://github.com/eliot2 what do I type in the terminal to change the file as you describe above? I still cant access trusty and get the same error as described here. Thanks in advance.

It looks like this issue got derailed a tad.

Instead of resolving the black screen with dbus errors we instead ventured into the one I mentioned in https://github.com/dnschneid/crouton/issues/2917#issuecomment-265191827

So the fix mentioned in https://github.com/dnschneid/crouton/issues/2917#issuecomment-267411158 will not help with this issue - as far as I know.

However it may help with this issue: Probably to do with xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted) #2926

Hope this helps, -DennisL
