[14:03] <xu-help14w> Hi I have a question about the start-up process of Xubuntu
[14:10] <diogenes_> !ask
[14:53] <anotheryou> Hi, I'm a bit new to linux still. Any way I could get the fix for this here earlier than with the next xubuntu release in ~oktober? https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1838151
[14:55] <anotheryou> In general, is there any way I should keep xubuntu updated between releases?
[14:57] <diogenes_> !upgrade
[15:00] <anotheryou> thanks diogenes_ . I'm up to date there :). Still would love to see this bug gone.
[15:01] <miu5> Hi, im having a bit of an issue the passed 2 months or so.  Everytime i update my packages via apt-get, after that i notice that all my file associations are fucked.  I have to then manually go and re-associate mp4's to open up with a specific player, pdf's to open up with a specific pdf reader, and well, you can see where im going with this...  Can anyone tell me what is causing the file disassociation everytime i update? Xubuntu 18.04
[17:11] <christophergray> miu5: update-desktop-database -v /usr/share/applications /usr/local/share/applications
[17:21] <miu5> christophergray, if i try that - is it going to change any commands or settings *within* some of the "app.desktop" files here /usr/share/applications/ ?
[17:23] <christophergray> miu5: it will just create new mimeinfo.cache files in those two directories
[17:24] <christophergray> from the info in the .desktop files
[17:24] <miu5> christophergray, ok, so is there a possibility that the mime.cache is corrupt?
[17:24] <miu5> is that why its doing this all the time?
[17:26] <christophergray> maybe there's something wrong with your XDG-DATA-DIRS so it is not finding your .desktop files on upgrade
[17:28] <christophergray> most of your .desktop files are probably in those two directories, so I suggested specify them instead of use default for update-desktop-database
[17:28] <diogenes_> miu5, is 'save session' enabled?
[17:31] <miu5> diogenes_, if you are asking if the "Automatically save session on logout" checkbox is checked in the session & startup UI, its not.  Is that what you were referring to?
[17:33] <diogenes_> that and also settings editor > xfce4-session > SaveOnExit must be disabled.
[17:36] <miu5> diogenes_, yes that one's also disabled.
[17:38] <diogenes_> also check the logs .xce4-session.verbose-log present. and .xsession-errors
[17:38] <diogenes_> .xfce4-session.verbose-log*
[18:12] <lisbeths> My webcam is not detected
[18:13] <diogenes_> lisbeths, how do you know? builtin? usb? more info please.
[18:13] <lisbeths> It is builtin to my laptop monitor
[18:14] <lisbeths> I know because chrome says no camera detected and so does the cheese selfie app
[18:14] <lisbeths> Sometimes it works and sometimes like now it does not detect. I have rebooted.
[18:15] <diogenes_> sudo apt install guvcview
[18:15] <diogenes_> see if it's detected there.
[18:17] <lisbeths> Guvcview error no device found
[18:18] <diogenes_> lisbeths, has it worked after system installation?
[18:19] <lisbeths> Yes. let me actually try in a live environment.
[18:19] <lisbeths> I will return
[18:21] <lisbeths> I did a hard reboot and booted to my usb but my usb was borked so it booted into grub. Then I rebooted again into my hard disc to go and redownload the iso. Now the webcam works.
[18:22] <lisbeths> I didn't jiggle the laptop monitor at all it is definitely a software issue, but now I have to reproduce it :(
[18:22] <diogenes_> lisbeths, i wouldn't say "definitely".
[18:22] <lisbeths> I mean not a connectivity issue in the wiring
[18:23] <lisbeths> cause I did burn the back of this laptop on a stove
[18:23] <lisbeths> but I hadn't adjusted the monitor at all during that reboot so I am fairly certain that it was forcing it to fully reboot the bios that had done it
[18:24] <lisbeths> the thinkpad forums say to press fn + f6 for this model to enable the camera however they say that opens up a "menu" but that "menu" is for windows not for linux
[18:24] <lisbeths> so I think perhaps there is some keybind I had hit on accident which had caused the camera to be disabled by the hardware itself
[18:24] <diogenes_> nobody can tell for sure what the problem is unless a thorough diagnose will be made.
[18:24] <lisbeths> yeah... well hopefully this "fix" of a super hard reboot is reproducable
[18:25] <lisbeths> I cant test it anymore till the webcam fails again and thats rare
[18:26] <lisbeths> oh well there's nothing left to do. Thank you for the help.
[18:28] <diogenes_> IRC client for Emacs heh.
[19:07] <miu5> christophergray, i tried that command, but i get an error:  Could not create cache file in "/usr/local/share/applications": Error opening directory ?/usr/local/share/applications?: No such file or directory
[19:08] <miu5> i remember i used to have /usr/local/share/applications,  but now im a bit confused as to why that folder is missing..
[19:09] <miu5> christophergray, am i supposed to run update-desktop-database with sudo ?
[19:10] <miu5> also this error:   Could not create cache file in "/usr/share/applications": Permission denied
[19:12] <christophergray> miu5: don't worry about the /usr/local/share/applications, it means you didn't install stuff from source
[19:13] <christophergray> miu5: try 'sudo update-desktop-database -v'
[19:16] <miu5> christophergray, it says lacks MimeType key for each one
[19:18] <christophergray> I get the same thing here
[19:25] <miu5> so does this seem like a bug though?
[19:25] <christophergray> do you get a list to choose from if you do mimeopen -a /usr/share/alsa/utils.sh
[19:26] <christophergray> I get a list of 17 apps
[19:52] <miu5> christophergray, i get the following:
[19:52] <miu5> WARNING: You don't seem to have any mimeinfo.cache files.
[19:52] <miu5> Try running the update-desktop-database command. If you
[19:52] <miu5> don't have this command you should install the
[19:52] <miu5> desktop-file-utils package. This package is available from

[19:52] <miu5> Please choose an application
[19:54] <miu5> sorry, here: https://bpa.st/raw/J45A
[20:56] <christophergray> miu5: try it again after 'sudo update-desktop-database /usr/share/applications'
[20:57] <christophergray> or better, ls -l /usr/share/applications/mimeinfo.cache, or locate mimeinfo.cache
[20:59] <christophergray> print $XDG_DATA_DIRS/applications
[21:08] <miu5> christophergray, doing ls -l cmd it found it -rw------- 1 root root Aug 28 18:58 /usr/share/applications/mimeinfo.cache
[21:09] <miu5> and when you said i should try it again after 'sudo update-desktop-database /usr/share/applications',   i did, and i got the same result. as in the link i sent you
[21:09] <christophergray> mine has -rw-r--r-- permissions
[21:12] <christophergray> looks like you need to change the permissions to 644
[21:16] <christophergray> miu5: sudo chmod a+r /usr/share/applications/mimeinfo.cache
[21:30] <christophergray> ls -l /usr/share/ | grep applications
[21:31] <christophergray> should show drwxr-xr-x    2 root root  12288 Aug 28 13:17 applications/

[21:55] <xu-help52w> evening
[21:55] <xu-help52w> im newbie switch from windows to linux and encountered a problem
[21:56] <xu-help52w> id like to stream from laptop to tv like i did on windows,is there an easy way to do this?
[22:02] <miu5> christophergray, do you know what wouldve changed my permissions?
[23:10] <christophergray> could have been the installer for the output of this command: ls -c /usr/share/applications | grep desktop | head -1
[23:10] <christophergray> miu5: or a buggy file system implementation, I just use ext4 here
[23:14] <christophergray> miu5: those are just wild guesses, though
[23:45] <miu5> christophergray, you still there?
[23:45] <christophergray> miu5: I'm back
[23:46] <miu5> christophergray, what do you mean by "could have been the installer for the output of this command: ls -c /usr/share/applications | grep desktop | head -1"   ?
[23:47] <christophergray> miu5: that shows the program last updated
[23:48] <miu5> christophergray, oh ok, but how do i know what was the program that changed the permissions? because i dont know when this even happened..
[23:49] <miu5> i mean is it possible to see when the permissions was changed?
[23:50] <christophergray> I don't really understand permissions much.  Are things working now?
[23:51] <miu5> christophergray, im also not sure if it should really show drwxr-xr-x    2 root root  12288 Aug 28 13:17 applications/ as you said... because i tried it on a fresh VM now and the VM says -rw-r--r-- 1 root root 16346 Jul 17 15:23 /usr/share/applications/mimeinfo.cache
[23:52] <miu5> well, no.. i mean i havent changed the permissions yet, cause i dont know what the actual default permissions should be..
[23:52] <christophergray> the drwxr-xr-x is for the folder '/usr/share/applications'
[23:52] <miu5> oh ok
[23:54] <christophergray> but that is probably okay since you can run apps
[23:54] <miu5> ok my '/usr/share/applications' is fine.. it wasnt modified
[23:55] <christophergray> the mimeinfo.cache needs to be readable by you, to work for you
[23:55] <miu5> do you think because the /usr/share/applications/mimeinfo.cache has wrong permissions thats why it keeps reverting back to default after apt-get update everytime ?.
[23:57] <christophergray> is there something in the mimeinfo.cache, sudo cat /usr/share/applications/mimeinfo.cache
