VectorLinux 7.2 Beta1 LIGHT [x86 64] ISO: How to Install and Use the Slackware-Based OS

when the xfce desktop is locked for longer time the screen goes black after typing the password to unlock. for shorter times the xfce desktop comes back, but one can already see something is not right since the background usually stays black while the panel is rendered slowly and then after some moments or after the mouse move the background is restored. when the desktop is locked for longer, like several hours with the notebook lid closed, the password prompt lights up correctly, but after entering the password screen goes all black. one can still switch to the VC, i tried to login and killed the xfce locker and the gnome-screensaver but this does not help since going back to the F7 VC still just switches to the black screen. there is no other option than to restart X or reboot from the linux VC.

DOWNLOAD

1. Add the Xubuntu Developers PPA to get the new packages: sudo add-apt-repository ppa:xubuntu-dev/ppa2. Update package information and update the two crucial packages "sudo apt-get update && sudo apt-get install xfce4-power-manager light-locker-settings"3. Restart your machine.4. Open light-locker-settings and make sure "Lock on suspend" is enabled (if it already is, disable and then re-enable it, then hit "Apply").5. Close your laptop's lid.6. You should be presented with the unlock screen upon opening the lid, login and you should see your desktop

@ochosiok, i have added the ppa you suggested and now instead of a black screen i get this pajama striped screen you can see in the attached photo. i can still go to VC and do "service lightdm restart" to login into a fresh xfce...

I did some independent research into this after smashing into this bug on elementary OS loki: the issues are documented on on the light-locker project page at -cavalry/light-locker but the source hasn't been touched since 2015, and the project seems to be in development hell with no developers or projects assuming ownership. the readme states:

Workaround that I use:* Open text terminal/virtual console (CRTL+ALT+F1)* log in* kill light-locker ($ killall light-locker)* go to XFCE terminal (CTRL+ALT+F7) (screen is still black)* close/open laptop lid (normal XFCE with all previously opened apps now shows)optional* run light-locker again in terminal to re-enable screen locking/sleep mode ($ light-locker)

If you do decide to use third party replacement batteries, please do notchoose the cheapest available generic SLA batteries. These batteries will,almost without exception, not last as long as brand namebatteries and will need replacing within 12-18 months instead of 3-5 years.Even when using brand name replacement batteries, make sure that you choosethe UPS version (aka "standby") which may cost slightly more,but which will last significantly longer in typical UPS usage (long periodsof standby punctuated with infrequent deep discharges).

When the UPS switches to the battery, the battery icon will appear in the system tray. While the UPS is online, if thebattery is not at least 99% charged, the plug icon will become aplug with a lightning bolt in the middle to indicate thatthe battery is charging.

Finally, double-check the state of your cabling and UPS indicatorlights frequently during testing. For voltage-signaling UPSes,apcupsd is not currently able to detect whether or not the serialcable is connected. In addition, some simple signaling UPSes withcertain cable combinations are not able to detect the low batterycondition. For more details please see Voltage Signalling FeaturesSupported by Apcupsd for Various Cables.

In principle, you should be able to do this with the computerpowered by the UPS, but if you wish to be completely safe, youshould plug your computer into the wall prior to performing theruntime calibration. In that case, you will need to artificiallyload the UPS with light bulbs or other means. You should supply aload of about 30 to 35% but not more than 50%. You can determinethe load by looking at the output of the apcaccess statuscommand while apcupsd is running.
