Starting lxqt the first time displays only a black screen with a few white icon boxes at the bottom of the screen. Once the theme and icon are explicitly set, the problem is resolved. Note this listing: firebook ~ # ls -la .config/lxqt/ total 36 drwxr-xr-x 1 root root 270 Mar 14 20:25 . drwxr-xr-x 1 root root 28 Mar 14 20:18 .. -rw------- 1 root root 28 Mar 14 10:40 desktop.conf -rw------- 1 root root 768 Mar 14 20:17 globalkeyshortcuts.conf -rw------- 1 root root 94 Mar 14 20:17 lxqt-powermanagement.conf -rw------- 1 root root 28 Mar 14 10:40 lxqt-runner.conf -rw------- 1 root root 92 Mar 14 20:25 lxqt.conf -rw------- 1 root root 28 Mar 14 10:40 notifications.conf -rw------- 1 root root 653 Mar 14 20:17 panel.conf -rw------- 1 root root 28 Mar 14 10:40 power.conf -rw------- 1 root root 28 Mar 14 10:40 session.conf The files with a timestamp of 10:XX were created when the first time lxqt was run. This is when there was only a black screen with several white icon boxes. The files with a timestamp of 20:XX were created when I updated the theme and icon settings. Then the user's ~/.config/lxqt/lxqt.conf file doesn't yet exist, it's supposed to fallback to the global file /etc/xdg/lxqt/lxqt.conf. It doesn't appear to do that resulting in the black screen and white icons. I've talked with upstream via irc at freenode #lxqt. They're looking at it but are not sure it's a packaging problem or part of the work in progress. The work arounds in related bug# 543380 work fine. i.e. emerge ogygen-icons if you don't already have them and explicitly set your theme and icon set.
I've been doing some testing wrt this. I can now reliably demonstrate the problem. # useradd -c 'Test for LXQT 01' -m test01 # passwd test01 (set a password of your choice) clt-alt-F2 (-F6) (open a new console) login: test01 password: XSESSION=lxqt startx -- :2 The leftmost bottom white box is the menu button. Click this. Fixed bug# 543380 will now show icons with the menu items. log out At the top of your screen (depending on how many lines your screen displays at one t time and how many status lines output by X) you should see the following message: Theme: Cannot open file for reading: "/lxqt-session.qss" I hope this helps.
This should be closed as latest versions of lxqt no longer exhibit this paticular behavior.
