I've been successful in re-creating this now in Debian Bullseye/sid on - dell [optiplex] 780 (c2q-q9400, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350)
(research aimed at filing upstream; versions of LXQt is identical to hirsute I believe) HOWEVER it took a lot of play before I could get this to occur. (on this regularly used system, I wasn't able to get it to occur like I have difficulty on my main Lubuntu hirsute install; it appears to be easier to produce on freshly installed systems; I had issues getting it to occur the first time on opensuse too. fear here is upstream may have trouble proving it). A theory for other like bugs has been it's a value not being set/initialized; that maybe at play however I got it to occur by changing LXQt's Monitor.Settings.Fast.Menu.Fast.Option so no openbox connection?? In the end I went into Monitor.Settings and used the Fast.Menu to to select Fast.Options and selecting Extended.View (which wasn't the in-use option at the time) and it appeared easily. This uploaded picture is print screen showing the fast.menu.fast.option.extended.view just being selected... Two displays, the panel on the bottom-left shows the position of the left.monitor the qterminal however is maximized on the right.monitor (portrait), and a GAP has opened up?? As Monitor.Settings reflects this; at this stage it's only a nuisance, however I'd not expect the gap to occur on selecting Extended.View in Fast.Menu->Fast.Options ** Attachment added: "Screenshot_20210327_122043.png" https://bugs.launchpad.net/ubuntu/+source/lxqt-session/+bug/1882411/+attachment/5481339/+files/Screenshot_20210327_122043.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1882411 Title: lubuntu monitor settings touching screens with gap between To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxqt-session/+bug/1882411/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
