[11:26] <xubuntu86w> Hi I have downloaded xubuntu-18.10-desktop-amd64.iso and installed on VirtualBox 5.2.22 on Windows, after boot I see garbled display as described in https://superuser.com/questions/1295202/garbled-display-when-running-lubuntu-17-10-as-guest-os
[11:26] <Cybertinus> xubuntu86w: try disabling 3D accelaration in your VM settings
[11:26] <xubuntu86w> it is not enabled
[11:27] <xubuntu86w> if I download and install xubuntu-18.04.1-desktop-amd64.iso everything is fine
[11:27] <Cybertinus> ok, then that's not it :)
[11:27] <xubuntu86w> so it looks like the problem is introduced with 18.10
[11:27] <Cybertinus> do you have the guest additions installed, or weren't you able to do that because you get this screen right away?
[11:29] <xubuntu86w> there is a workaround : Press Ctrl-Alt-F2 to switch to text terminal and then Ctrl-Alt-F7 to switch back to GUI
[11:29] <xubuntu86w> no I do not have guest additions
[11:30] <Cybertinus> the two tips specified in the topic you just link don't help too, I assume?
[11:30] <Cybertinus> well, try installing the guest additions
[11:30] <xubuntu86w> let me check
[11:32] <Cybertinus> I have to go afk now, be back in an hour or so, I think
[11:33] <xubuntu86w> ok I will report my experiments with the hints hereafter
[11:38] <xubuntu86w> only setting video memory to 128MB has no effect
[11:47] <xubuntu86w> disabling nested paging (system -> acceleration -> enable nested paging checkbox) AND increasing the video memory to 128 mb (display -> video memory slider) : in this case for 1 second the screen is displayed correctly then it becomes garbled
[12:06] <Unit193> Typically when I've seen that, flipping to a TTY and restarting lightdm fixes it.

[21:35] <irgendwer4711> hi, after upgrading to 18.10, Firefox download window does not work any more, no files are opened
[22:57] <irgendwer4711> any one?
[23:09] <guiverc> irgendwer4711, i don't use it (I usually wget my files), how do you get to the firefox download window  (I'll have a look & see how it is for me)
[23:10] <irgendwer4711> main gui
[23:10] <irgendwer4711> download button
[23:11] <guiverc> i don't have one; maybe it appears when you first download (and I haven't yet)
[23:11] <irgendwer4711> no
[23:15] <guiverc> okay found it ; library->downloads - on mine it just opens thunar when i click 'downloads'
[23:15] <guiverc> (thunar $HOME/Downloads/)
[23:16] <irgendwer4711> I tried another firefox profil and the problem is there too,.
[23:17] <irgendwer4711> hm I see, could be an apparmor problem
[23:17] <guiverc> i don't know enough about firefox sorry.  if it were me I'd try `sudo apt install --reinstall firefox` (which is likely to change nothing), then create new user id; & try from there (If that works okay; it's likely a config issue in your profile/settings saved in your user directory; but I'm guessing only as I don't know
[23:19] <irgendwer4711> its apparmor
[23:21] <guiverc> you could ask in #ubuntu (please only ask in a single room though or wait before asking in another room; I can't help with apparmor sorry)
[23:23] <irgendwer4711> ok
