Problem description:

xubuntu 18.04.1 on HP Stream 13 starts to display xfce panels, pauses and then repeatedly blanks and resets the screen. Sometimes it displays the login screen even though the login screen should be bypassed because I don't require a password.

I have been using this system with xubuntu 16.04 (either version 1 or the original release - not sure) without problems. The live CD for 16.04.3 works as expected, but the live CD for 16.04.4 and 16.04.5 have the same (or similar) problem.

In kern.log I see: [drm] GPU HANG: ecode 8:0:0x0fdfffff, in Xorg [718], reason: Hang on rcs0, action: reset

Multiple gpu resets follow. In this boot, I have attempted to turn off acceleration with the following two configuration files. It gets a little further with the manual Xorg configuration, but the behavior is much the same. With the manual configuration, it will display the top bar (panel), put a few widgets on it at the right side, and usually display the mouse icon in the upper left corner. Sometimes it displays the wavy background image for ubuntu 18.04, but with irregular chunks of the image missing.

With or without the xorg.conf files I get the GPU HANG message as above.

Attempts to turn off modesetting don't work either - I get a white screen background with what look like Thai characters - even during the boot messages (I remove "quiet" and "splash" from the grub command line).

It could be that I'm not turning off modesetting correctly, so perhaps it would be best to send me instructions on how to do that.

/etc/X11/xorg.conf.d/20-i915:

Section "Device" Identifier "Intel Graphics" Busid "PCI:0:2:0" Driver "vesa" Option "NoAccel" "true" # An alternate: Option "DRI" "False" # An alternate: Option "AccelMethod" "sna" # An alternate: Option "AccelMethod" "uxa" EndSection

and /l/tr/etc/X11/xorg.conf.d/90-disable-glx

Section "Extensions" Option "GLX" "Disable"

Option "DRI" "Disable"

Option "DRI2" "Disable"

Option "DRI3" "Disable"
