bluesabreali1234: I don't suppose you know of min/max mouse acceleration options with xorg? Can't seem to find any docs on it. Related to https://bugzilla.xfce.org/show_bug.cgi?id=1262200:01
ubot93Xfce bug 12622 in Xfce4-settings "mouse acceleration capped at 10" [Normal, Assigned]00:01
ali1234i don't know but the acceleration slider in mouse settings seems to have no effect for me03:41
bluesabreali1234: that's seemingly related to libinput09:53
brainwashbluesabre: having it built with libinput support in some ppa would help to test it10:06

TJ-This week I discovered a security vulnerability in the screen-lock/hide desktop functionality. When there are multiple X screens the lock only operates on :0.0. Contents of other X screens remain visible. This reminded me of the same bug I reported in 2013 (!) in KDE which has still not been fixed. Where best to report this against? Presumably upstream but not sure which project/package. ( Bug #126482111:22

bluesabreTJ-: light-locker would be the project I believe, https://github.com/the-cavalry/light-locker would be the upstream11:40
ochosi(fairly dormant upstream, tbh)11:42
TJ-hmmm, it looks like it should just be dropped! combined with the other LL bug where lid-induced suspend results in 'dead' tty on resume!11:44
TJ-It really annoys me, devs working on core display technology don't test on multiple X screens - which is a very common scenario in enterprises especially.11:45
TJ-I'll look at it in more depth next week11:55
bluesabreI've considered in the past porting gnome-screensaver to xfce11:56
bluesabreworks well as a lock screen, and switch user works11:56
bluesabrenot tried with multiple X screens, but likely has better support than light-locker11:57
bluesabreeven though ll was originally based on it11:57
ochosiyou can simply go to one of the first revisions when i was still contributing a bit more12:06
ochosithat's basically gnome-screensaver without gnome depends12:06
ochosi(and that was my original idea)12:06
bluesabreneat12:08
ochosiit was usable and working12:08
brainwashbluesabre: I'm curious about this one also https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/xfce4-settings&id=a1a6ca07f0577a62b8e6679ee023eea774502d8e18:26
brainwashthis was linked in a launchpad report18:27
brainwashwhat would not building with upower support break?18:28
brainwashxubuntu users often mention the workaround to edit /etc/UPower/UPower.conf, and do IgnoreLid=false ==> IgnoreLid=true18:32
brainwashas workaround for that black screen thing18:32
bluesabrebrainwash: I don't know the answer to that. As far as I know, some laptops report to Upower one value, while others do the reverse18:38
bluesabreochosi may know more18:38
brainwashthe archlinux people do not seem to have any major problems with their builds18:39
brainwashat least they did not revert that linked commit18:40
brainwashI'd think that systemd can handle those events18:41
brainwashlid close/open18:41
TJ-interesting; that's the bug I originally reported. Not revisited it since, I just manually suspend before closing the lid18:41
brainwashyou mean bug 1431149 ?18:42

brainwashstill open18:43
brainwashupstream I mean18:43
TJ-light-locker upstream is basically abandonware so far as I could tell18:44
brainwashit does look like it18:44
TJ-I did a lot of source-code diving/debugging and narrowed it down some, but never got to looking at upower. If I can find some time this week I'll investigate that lead and report back in my bug report18:45
brainwashI recall that getting rid of VT switching was on the roadmap18:45
brainwashsadly, no progress18:45
TJ-what I found was that in the LidClose event case, the number of Close events didn't match the number of Open events after resume, which seemed to leave the X server state as DPMS off or something. My memory is quite sketchy without re-reading my notes18:47
brainwashis that with xubuntu only?18:47
TJ-yes18:48
TJ-I also noticed it seems to be timing related, in that for me at least, faster CPUs seemed to suffer it more than slower ones. Not sure if that was just co-incidence though - I didn't do rigorous tests of that!18:48
brainwashmaybe building -settings without upower could somehow help18:49
brainwashI assume that would mean that upower is not pulled in anymore18:50
brainwashwait. the power-manager needs it still, or?18:50
brainwashthis really requires a proper investigation =S18:51
TJ-looking at the source, it provides a dbus service for x-p-m 18:54
brainwashah19:01
brainwashdoes x-p-m really need that service?19:02
brainwashI assume that it can fall back to systemd19:02
TJ-I've just spotted a bug in upower, reporting the battery state as 208% of design capacity19:03
brainwashthat's called 'supercharged'19:03
TJ-note line 45 vs line 5: http://paste.ubuntu.com/p/bphCcjmFbd/19:05
Spasson 18.10 I have problems with whoopsie - https://ibb.co/jYT0ue19:12

Unit193< bluesabre> works well as a lock screen, and switch user works   I think you just described xscreensaver? :P19:20
bluesabreUnit193: didn't you share that xscreensaver sometimes doesn't show for folks now :D19:20
Unit193Oooh dang, you do read me. :3  And yeah, login screen tends to flash for a second then goes away, but esc out of it and move mouse again to bring it up.19:22
Unit193And only Xfce folks! :P19:22
knomeUnit193's new motto: "Use GNOME, people!"19:23
bluesabremy new motto: Use knome, people!"19:23
knomeuhhh19:23
bluesabre:D19:23
Unit193Pretty sure that'd be the last thing I'd say.19:23
bluesabre:D19:23
knomei'm sure you didn't intend it to be interpreted as i did..19:23
bluesabreprobably not19:24
knome(:19:24
Unit193Besides, there's Xfce people here, that might be an Xfce specific problem, maybe one of them can fix it! :D19:55
bluesabre:D20:02
