Display manager GUI invisible

grahamperrin commented 7 years ago

Intel HD Graphics 5500

HP EliteBook 850 G2

Tuesday 2016-12-20 around 09:25. After allowing Display Settings (if I recall correctly, pc-xgui launched automatically following updates to the OS) to apply an apparently good configuration (IIRC one of the Intel options at 1,920 x 1,080):

PCDM presented only the desktop background, no GUI.

The OS responded properly to Escape, both external displays (DisplayPort, HP dock) presented the shut down confirmation dialogue:

img_20161220_092828

Side note: blackness, not greyness, at the integral display.

I keyed Control-Alt-F2, logged in as root, set aside the most recent offending file and automated backup:

xorg.conf.txt xorg.conf.bak.txt

Prepared workaround

At /etc/X11/xorg.conf-2016-12-09 I keep a copy of a superior .conf file –

– that probably originated in August 2016 –

– and with the name given by me (xorg.conf-2016-12-09, not a .bak) I know that the kernel mode-setting goodness will not be overwritten by the OS.

With #189 I can not use Display Settings to recreate the KMS goodness, so I copied xorg.conf-2016-12-09 to xorg.conf` and then restarted the OS. Result:

img_20161220_093806

– both external displays driven – greyness at the integral display (a separate issue, presumably upstream in Linux).

Intel Graphics HD 3000

Lenovo x121e, Sandy Bridge Core i3

From Some problems/bugs after upgrade from pcbsd to / using TrueOS-Desktop-2016-12-15-x64-USB.img:

… PCDM: With external display there is no login GUI - neither on the main display (laptop/netbook) nor on the external one.

– that's consistent with Display manager GUI invisible (the subject of this issue), and –

Login GUI only displayed if external display is disconnected and pcdm is reloaded. –

– I assume that in the absence of the login GUI, the reload was performed from a root console e.g. Control-Alt-F2. (Or in this Lenovo x121e case, was the power menu visible? I'll seek clarification.)

I can't provide Xorg.0.log for the incident above (sorry; the need to use the machine for work overtook the wish to gather information for troubleshooting). Maybe when I'm next at work, in January.

This has been a longstanding issue with pc-xgui. We should adjust it to do no more than swap conf files present in /usr/local/share/trueos/cardDetect/ to /etc/X11/xorg.conf. We need to clean up, and make that directory consistent as well with the menu options pc-xgui provides.

Smart. Thanks.

Incidentally –

… longstanding …

I refrained from reporting issues such as this for a long time because of the additional peculiarity that affects e.g. the HP EliteBook 850 G2: there's never a display manager at the notebook (update).
