[01:25] <u19809> hi all, I have just upgrade to 20.04 and have serious paint problems on most apps (not all).  E.g when I start vlc or virtualbox the screen is not alive in that if I resize the window, the content is not adjusted and sometimes painted serveral times over. Also the content is not clickable at all
[01:26] <u19809> I have this problem in : dragonplayer, vlc, kate, virtualbox, chrome
 Which video card?
[01:26] <u19809> nvidia - sigh
 And driver version?
[01:27] <u19809> 440
[01:28] <u19809> nvidia-settings shows 400.100
[01:28] <u19809> Geforce GTX1050TI
 What render mode in System Settings -> Disp. Config.  -> Compositor -> Rendering backend
[01:29] <u19809> opengl 3.1 (with message that it caused a crash in the past)
 Did you have a re-enable button?  Sometimes kwin crashes hard and messes up the rendering state.  Re-enabling and logging out/in usually fixes things.
[01:32] <u19809> yes i do and will reenable and login/logout.  The problem occurs always after resume from suspend. Also the background of the desktop and logon screen is then black
[01:33] <u19809> reenabled and  rebooting after your response
[01:33] <u19809> here is a screenshot of a window with messed up content : https://pasteboard.co/JoZIeq8.png
[01:44] <u19809> just rebooted but paint issues still remain.  I also updated backed to xrender and logged out and in again but again paint issues.... :(:(:(:(:(
[01:44] <u19809> it blocks me as I need virtualbox to start a VM but because of the paint problems VBox is unusable
 Compositing enabled?
[01:45] <u19809> enabled yes
[01:45] <u19809> disable ?
 No
[01:45] <u19809> setup is dual display FWIW
 Hmmm.  You could try purging and re-installing the NVidia drivers or upgrade to the 450 driver.  The 450 has several bug fixes: https://www.nvidia.com/Download/driverResults.aspx/160555/en-us
 If you unplug one display, does the problem go away?
[01:47] <u19809> ok I will upgrade to the 450 ... I presume the upgrade would uninstall the 440 ?
[01:49] <u19809> if I disable my second monitor the problem goes away !!!!!!!!!!!!!!!!!!!!!!!
[01:49] <u19809> (disable from settings )
[01:49] <u19809> and also video starts to play (before nor vlc nor dragonplayer were able to play video )
[01:51] <u19809> ok, this is good ... I just reenabled the second display and again ... all is messed up.  I must say that my two monitors do not have the same resolution, one is 4K the other FullHD
 Under Nvidia Settings -> X server XVideo Settings  try changing the default sync device...
 ^^^ totally guessing here ^^^
 So does everything work on either monitor as long a the other monitor is disabled?
[01:53] <u19809> only tested on the 4K monitor (disable the FHD one).  sync does not seem to work
[01:54] <u19809> I have not logged out when changing sync.  should I ?
 Most of the NVidia settings do not require loggout...
 Under NVS -> OpenGL Settings have you tried toggling Allow Flipping or any of those options?
 Note, the hover help often specifies if the setting applies immediately.
[01:57] <u19809> sync to vblank is on, flipping off, use conformant texture mapping on,
[01:58] <u19809> image settings : quality
 For reference, I have Flipping on, Image Settings:  High Perf.  ( using a 4K and 2K monitor where 2k monitor is scaled to 4k and running at 144Hz).
[02:01] <u19809> ok ... will try and logout
[02:03] <u19809> ok, flipping does not seem to help but I had another thing. I have global scaling set to 175 and when I set it to 100 % the problem disappears.  when I set scaling back -> messed up
 Oh yes! Use Font to change the size of everything using X.  Wayland scaling is much better, but very difficult to enable using NVidia.
 The reason I run my 2k scaled to 4k is that sizes font and windows size match across monitors.
 However, scaling 1080p to 4k is a bit blocky for my preference (2K to 4k is very useable).
[02:08] <u19809> i do not see how to scale an individual monitor.  on 19 you had indivudual scrollbars for each of the displays, now there is just 'global'
 Yes, correct. Only under Wayland does the per display scaling work.
[02:10] <u19809> I do not mind using wayland but is it already operational for KDE ? I read that there were still open issues ...
[02:10] <u19809> logging out again
 Not until Qt 15.xxx is available will Wayland run using NVidia and proprietary drivers.
[02:13] <u19809> back
[09:58] <HiddenDjinn> i'm having some issues with jack and a usb audio interface
 @Zoth_Ommog, I got this problem again
 I forgot how to clear the cache
 Someone pls help
 Cleaning command didn't help
 Oh
[13:09] <BluesKaj> Hi all
 How r u blueskaj
 I even tried apt-cache pkgnames but it just shows no space left on device
 Do I need to nuke my files
 I don't understand why Kubuntu can let this happen
[13:14] <BluesKaj> o/ @Swift110, Zoth_Ommog
 Welp guess I'll reformat then
 Anyone got any method to prevent this from happening
 Try clearing the log files.  I have seen 3 different 20.04 installs where the log files hit 12GB or larger.
 How?
 I can only access terminal
 how big is the syslog file (ls -alh /var/log/syslog )
 316k
 It's the apt/archive that is chock full
 have you already ran sudo apt autoremove ?
 Yes
 autoclean too
 clean did nothing at all
 If you run df -lh, how big is your root directory?
 (Photo, 668x500) https://irc-attachments.kde.org/0XDbOwNp/file_35516.jpg
 oh crap, 14G is a little small these days for a root directory.
 Really? Dammit
 Devs assume everyone has lot of hd space and packages are starting to bloat.
 I haven't had time to switch /home to the hdd
 What's the recommended size nowadays
 That depends on what you install.  If you install apps like Anaconda and android-studio (I install to my /opt directory) they consume 7.5GB and 1.3GB resp.  Wine-staging is about a 1GB. Zoom,  Teams,  Chrome are around 300MB each so they all add up quickly.
 Do you run any VM's?
 Nope
 The most I do is kernel building
 For android
 Even then I only use the /home partition to do it
 Many build process use /tmp so may that be part of the issue.  Usually /tmp is cleared on reboot.
 try this sudo find /var/log -type f -size +1000M
 I want to ensure none of the log process ran wild...
 Didn't work
 Nothing was returned or error reported?
 Nope
 run the same command from root: sudo find / -type f -size +10000M
 Wait too many zeros:  sudo find / -type f -size +1000M
 (Photo, 668x500) https://irc-attachments.kde.org/4LEeLQpZ/file_35519.jpg
 ls -alh the last file on the list.
 Nope
 ls -alh /sys/kernel/debug/dri/0/admgpu_vram
[14:07] <lundrvs> I am reading a tutorial for programming in C++. And I find this point:
 how big is that file
[14:07] <lundrvs> "Add "/usr/include/freetype2" when it is in Linux. (The path of freetype2 may be different, it depends on your system)."
[14:08] <lundrvs> does anyone know what is "freetype2"?
 @DarinMiller, 4gb
 Amazing
[14:09] <lundrvs> or how is it named in Kubuntu?
 Will uninstalling amdgpu alleviate it a bit?
 I would try removing /sys/kernel/debug/dri/0/admgpu_vram
 then run sudo apt update and sudo apt full-upgrade
 Is it safe though
 I installed it from a amdgpu zip file
 I don't know, but it's in a debug directory and your system is already non-bootable.  You could try uninstalling amdgpu and see if the file goes away.
 nm, bad advice, that file is not deleateable: https://askubuntu.com/questions/972624/how-to-delete-debug-files-in-sys-kernel-debug
 Ah lawd
 Amdgpu uninstall fixed it
 Very good. I still recommend increasing the size of your root partition so that you have a little more breathing room.
 Yeah, I'll get a new HDD this weekend to give myself some space
[16:18] <resophokles_> has anyone successfully installed and run Zak McKraken on Kubuntu?
[16:18] <resophokles_> I don't mean the original, but the fanmade sequel
[16:21] <resophokles_> nevermind, just found a solution
[16:21] <genii> The original ran fine in real mode under dosbox. Dunno about the sequels
 @resophokles_, Please tell...
[16:30] <resophokles_> well there is a linux version for the sequel

 (Photo, 1280x689) https://irc-attachments.kde.org/FdUJWAp6/file_35531.jpg Hi, in Kubuntu 20.04 Okular cannot open .cbr files and it doesn't create the thumbnails in dolphin either. Any help?
[17:18] <genii> This is usually what it does when urnrar is not installed
[17:18] <genii> unrar ...rather
[17:20] <oerheks> no thumbnails from archives is pretty logical ? https://itsfoss.com/how-to-run-cbr-files-in-ubuntu/
 @genii, Oh thanks a lot! I install unrar and now work like a charm (thumbnails included)
[21:22] <bruhhh> hey there gamers
 hi
[21:23] <bruhhh> oh what are you guys real people? I've never used this app before
 Konversation or Telegram or another chat client
[21:23] <bruhhh> lol k
 What app are you using to hit this channel?
[21:25] <bruhhh> I misclicked Konversation on kubuntu
 ah, very good.
[21:25] <bruhhh> yeah this is cool tho
 This channel can also be accessed via Telegram (or other IRC clients)
