First of all, thanks to the devs for an excellent release! I'm on a real potato, an Acer Cloudbook 14 AO1-431 with a terrible Celeron N3060, 2GB of un-upgradable soldered on RAM and a 32GB soldered on and un-upgradeabe eMMC drive. I tried a minimal installation of Kubuntu 18.04 first, since there was lots of talk of Plasma's low RAM and CPU usage in this thread; in my testing this was also true at first (about 350Mb used and minimal CPU usage), and MX-19 Beta 1 was more like 400-450Mb, but MX-19 seems a lot better at memory management once I open a few tabs of Firefox (I setup zram on both the Kubuntu and MX19 installs - one device per CPU core (so two), each one being about 700Mb, which is using the default SysV /etc/init.d/zram config as detailed in the Debian Wiki:
https://wiki.debian.org/ZRam). Kubuntu just locked up after a while, and I had to force power off as I couldn't even get a tty1 to pkill the session. While MX19 chugs if I
really push it, it has a lot more mileage for me compared to Kubuntu.
One problem: when I suspend this machine, it often crashes on wakeup after I've put my password in. As others have noted, the default on MX19 Beta 1 is that "Enable Lock Screen" under "Whisker Menu>XFCE4 Screensaver>Lock Screen tab" is
not selected. At first, when suspending and resuming, there was no lock screen at all! I've enabled it, along with "Lock Screen with Screensaver" and "Lock Screen with System Sleep". It doesn't always crash after I put my password in after resuming from suspend, but it does often enough to be a little bit annoying. I have to go to tty1 with Ctrl+Alt+F1, login as my user, then select
but obviously this creates a new session, meaning anything I had open on suspend is gone. Not a massive issue, as I usually clean everything up and close every running program before suspending as a rule, but it is annoying. There are some upstream bugs open for xfce4-screensaver (which I know is new for XFCE 4.14) on the XFCE Bugzilla, but people request the output of
which doesn't work as I'm not running systemd. I was under the impression SysV doesn't keep logs in the same way? Happy to pull some out if anyone can give me some pointers...
**EDIT** This actually also happens when the screensaver activates while the machine is still on - I move the mouse, the lock screen (lightdm?) appears, I put my password in, and then everything freezes. Have to tty1 and force a restart of lightdm to get out of it, which starts a new session, losing anything I had open.
