Proposed as a Blocker and Freeze Exception for 23-final by Fedora user roshi using the blocker tracking app because: I believe this bug violates the following criteria: "Shutting down, logging out and rebooting must work using standard console commands and the mechanisms offered (if any) by all release-blocking desktops." ~ Beta "All applications that can be launched using the standard graphical mechanism of a release-blocking desktop after a default installation of that desktop must start successfully and withstand a basic functionality test." ~ Final A very similar problem is in GDM (again only in VM) - the cursor gets invisible. You can still interact with it, if you manage to put it over some button, but it's invisible. Created attachment 1084701 [details]
list of installed packages (rpm -qa)
this is most likely not a *DM issue. I'd speculate it's driver related. Are both of you using KVM? or some other VM mechanism? Created attachment 1084707 [details]
system journal
This is system journal after I log out and see gdm with invisible mouse cursor.
I'm using virt-manager with KVM. When I change video driver from QXL to VMVGA, the cursor does not disappear and works correctly. When I change it to VGA, I don't see cursor even on first boot. When I change it to Cirrus, Fedora does not boot at all. This is all tested with GDM. When I boot with nomodeset and using QXL in VM configuration, mouse cursor is shown properly after log out. I'm not exactly sure where to assign this, moving it to qxl xorg driver, in hope it's close. Quite interestingly I can't reproduce this with sddm, as Mike did. I'm using the same configuration VM (spice+qxl), and tested both F23 TC11 installed and fully updated from updates-testing (so the same as I used with gdm), but I see mouse cursor correctly on logout. So for me, only gdm is affected. Well, I just logged out of the KDE install I did yesterday to test the update notification stuff, and didn't reproduce it there. Will try a few more times. It would be good to know if anyone sees this on bare metal, too. Can't reproduce on bare metal with SDDM either. Installed TC11 KDE x86_64 live, created a user in g-i-s, logged in and out several times, never lost the cursor. It's notable that after logging out and before I touch the mouse again, the cursor is invisible, but as soon as I move the mouse at all, it appears. I can click all over the screen and nothing makes it disappear. Do you guys have a tablet virtual input device attached to your VM? Is your host F22 or F23? Can you try creating a brand new VM from scratch (to get the latest default config) and see if it changes the results for either case? From a freshly installed VM (which is what I used to verify my initial findings) I do have a tablet attached to it. This is from an F22 host. Even with the tablet removed, the cursor still vanishes. My host is F23, which I guess could be affecting things somehow. My VM has a tablet device. And I still don't see the problem on either GNOME or KDE. I'll try an F22 host... Nope, still can't reproduce this with a brand new VM in an F22 host. I dunno what you guys are doing, but it ain't happening to me. I'm starting to think that I and Mike are seeing two different issues. But I probably uncovered the mystery of my case. In my case, it seems to be a regression of bug 1200901 (which seem to not have been properly solved, just worked around in mutter) under Wayland. Same as in bug 1200901, if I remove "EvTouch USB Graphics Tablet" from VM configuration, the problem does not occur (but I lose seamless mouse integration in GDM and the movement gets jerky). However, even if I keep the tablet device present, and simply disable Wayland for GDM, the problem is also fixed (and I continue to have seamless mouse integration and smooth movement). So, at least in my case, it seems that bug 1200901 regressed, but in very specific cases - just for Wayland, and only after logout (the initial Wayland GDM shows cursor just fine). When I tried nomodeset or some other video drivers, I suppose GDM started in X mode instead of Wayland mode, so that could match those findings as well. I also found out that if press Enter in the GDM to show the password field and then move your invisible cursor over the password box (it's quite easy to hit it), the cursor re-appears, probably because of changing shape (over the text field). I tried testing the same approach with sddm (adding or removing tablet device), but I can't reproduce missing cursor in there (and I haven't found any option to make sddm run over Wayland).

livbirt xml with disappearing cursor
Fresh new F23 libvirt machine created, this is its XML, which exhibits the missing cursor on logout. Running on F23 host.
Well, I'm using GDM-on-Wayland too, and all my VMs have tablets. Created attachment 1085047 [details]
libvirt xml with not disappearing but jerky and not seamless cursor
This is the same libvirt XML, but a tablet device was removed, and it "fixes" the missing cursor with Wayland GDM (but breaks mouse seamless integration and smooth movement).

Huh - somehow with RC2 I've started seeing the 'missing cursor after logout from GNOME' bug in a freshly-created F23 hosted VM. Cursor is clearly active but invisible. Started happening after two logouts. The GNOME case for me here is fixed with mutter-3.18.1-4.fc23 - http://koji.fedoraproject.org/koji/buildinfo?buildID=693553 . The KDE and GNOME cases should probably be tracked separately - they may be somewhat *related*, but the mutter fix certainly will not fix KDE. I'll split out another report for GNOME. Actually, we'll use #1200901 for the GDM case, as it's been there all along. I've nominated that as blocker/FE. For KDE/SDDM devs: there's some discussion of the underlying cause of the GNOME case in https://bugzilla.redhat.com/show_bug.cgi?id=1200901 . additionally, halfline says: but the fix is just a workaround for a kernel bug but i think the x server already has a workaround in it so it really only affects wayland well it could be the x server doesn't always do the workaround, like we aren't always doing it in which case the kernel patch would address both so, you might want to check the other bug and see if the KDE case looks like it's caused by the same underlying kernel bug and the X workaround isn't always working, I guess? halfline ultimately wants this fixed in the kernel, but for now he's applying a workaround to mutter, so a similar workaround in the KDE stack may be possible - again, *if* the cause actually is the same. Discussed at 2015-10-22 Go/No-Go meeting, acting as a blocker review meeting: https://meetbot-raw.fedoraproject.org/fedora-meeting-2/2015-10-22/f23-final-go_no_go-meeting.2015-10-22-16.00.log.txt . Rejected as a blocker, but accepted as a freeze exception issue: as with the GDM case, this is annoying but fairly easy to work around, keyboard navigation isn't too hard. Common bugs note and an update fix would be sufficient, but if we find a safe fix in time we would consider it. Removing CommonBugs nomination, F23 is out. This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
