u19809hi 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 all01:25
u19809I have this problem in : dragonplayer, vlc, kate, virtualbox, chrome01:26
IrcsomeBot<DarinMiller> Which video card?01:26
u19809nvidia - sigh01:26
IrcsomeBot<DarinMiller> And driver version?01:27
u19809nvidia-settings shows 400.10001:28
u19809Geforce GTX1050TI01:28
IrcsomeBot<DarinMiller> What render mode in System Settings -> Disp. Config.  -> Compositor -> Rendering backend01:28
u19809opengl 3.1 (with message that it caused a crash in the past)01:29
IrcsomeBot<DarinMiller> 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.01:31
u19809yes 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 black01:32
u19809reenabled and  rebooting after your response01:33
u19809here is a screenshot of a window with messed up content : https://pasteboard.co/JoZIeq8.png01:33
u19809just rebooted but paint issues still remain.  I also updated backed to xrender and logged out and in again but again paint issues.... :(:(:(:(:(01:44
u19809it blocks me as I need virtualbox to start a VM but because of the paint problems VBox is unusable01:44
IrcsomeBot<DarinMiller> Compositing enabled?01:44
u19809enabled yes01:45
u19809disable ?01:45
IrcsomeBot<DarinMiller> No01:45
u19809setup is dual display FWIW01:45
IrcsomeBot<DarinMiller> 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-us01:46
IrcsomeBot<DarinMiller> If you unplug one display, does the problem go away?01:47
u19809ok I will upgrade to the 450 ... I presume the upgrade would uninstall the 440 ?01:47
u19809if I disable my second monitor the problem goes away !!!!!!!!!!!!!!!!!!!!!!!01:49
u19809(disable from settings )01:49
u19809and also video starts to play (before nor vlc nor dragonplayer were able to play video )01:49
u19809ok, 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 FullHD01:51
IrcsomeBot<DarinMiller> Under Nvidia Settings -> X server XVideo Settings  try changing the default sync device...01:52
IrcsomeBot<DarinMiller> ^^^ totally guessing here ^^^01:52
IrcsomeBot<DarinMiller> So does everything work on either monitor as long a the other monitor is disabled?01:53
u19809only tested on the 4K monitor (disable the FHD one).  sync does not seem to work01:53
u19809I have not logged out when changing sync.  should I ?01:54
IrcsomeBot<DarinMiller> Most of the NVidia settings do not require loggout...01:54
IrcsomeBot<DarinMiller> Under NVS -> OpenGL Settings have you tried toggling Allow Flipping or any of those options?01:56
IrcsomeBot<DarinMiller> Note, the hover help often specifies if the setting applies immediately.01:57
u19809sync to vblank is on, flipping off, use conformant texture mapping on,01:57
u19809image settings : quality01:58
IrcsomeBot<DarinMiller> 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).02:00
u19809ok ... will try and logout02:01
u19809ok, 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 up02:03
IrcsomeBot<DarinMiller> Oh yes! Use Font to change the size of everything using X.  Wayland scaling is much better, but very difficult to enable using NVidia.02:05
IrcsomeBot<DarinMiller> The reason I run my 2k scaled to 4k is that sizes font and windows size match across monitors.02:06
IrcsomeBot<DarinMiller> However, scaling 1080p to 4k is a bit blocky for my preference (2K to 4k is very useable).02:07
u19809i 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'02:08
IrcsomeBot<DarinMiller> Yes, correct. Only under Wayland does the per display scaling work.02:09
u19809I do not mind using wayland but is it already operational for KDE ? I read that there were still open issues ...02:10
u19809logging out again02:10
IrcsomeBot<DarinMiller> Not until Qt 15.xxx is available will Wayland run using NVidia and proprietary drivers.02:11

IrcsomeBot<Zoth_Ommog> @Zoth_Ommog, I got this problem again11:45
IrcsomeBot<Zoth_Ommog> I forgot how to clear the cache11:45
IrcsomeBot<Zoth_Ommog> Someone pls help12:37
IrcsomeBot<Zoth_Ommog> Cleaning command didn't help13:05
IrcsomeBot<Swift110> Oh13:07
BluesKajHi all13:09
IrcsomeBot<Swift110> How r u blueskaj13:10
IrcsomeBot<Zoth_Ommog> I even tried apt-cache pkgnames but it just shows no space left on device13:11
IrcsomeBot<Zoth_Ommog> Do I need to nuke my files13:11
IrcsomeBot<Zoth_Ommog> I don't understand why Kubuntu can let this happen13:11
BluesKajo/ @Swift110, Zoth_Ommog13:14
IrcsomeBot<Zoth_Ommog> Welp guess I'll reformat then13:17
IrcsomeBot<Zoth_Ommog> Anyone got any method to prevent this from happening13:18
IrcsomeBot<DarinMiller> Try clearing the log files.  I have seen 3 different 20.04 installs where the log files hit 12GB or larger.13:19
IrcsomeBot<Zoth_Ommog> How?13:19
IrcsomeBot<Zoth_Ommog> I can only access terminal13:20
IrcsomeBot<DarinMiller> how big is the syslog file (ls -alh /var/log/syslog )13:22
IrcsomeBot<Zoth_Ommog> 316k13:24
IrcsomeBot<Zoth_Ommog> It's the apt/archive that is chock full13:25
IrcsomeBot<DarinMiller> have you already ran sudo apt autoremove ?13:30
IrcsomeBot<Zoth_Ommog> Yes13:31
IrcsomeBot<Zoth_Ommog> autoclean too13:31
IrcsomeBot<Zoth_Ommog> clean did nothing at all13:31
IrcsomeBot<DarinMiller> If you run df -lh, how big is your root directory?13:38

IrcsomeBot<DarinMiller> oh crap, 14G is a little small these days for a root directory.13:42
IrcsomeBot<Zoth_Ommog> Really? Dammit13:42
IrcsomeBot<DarinMiller> Devs assume everyone has lot of hd space and packages are starting to bloat.13:43
IrcsomeBot<Zoth_Ommog> I haven't had time to switch /home to the hdd13:43
IrcsomeBot<Zoth_Ommog> What's the recommended size nowadays13:44
IrcsomeBot<DarinMiller> 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.13:50
IrcsomeBot<DarinMiller> Do you run any VM's?13:50
IrcsomeBot<Zoth_Ommog> Nope13:52
IrcsomeBot<Zoth_Ommog> The most I do is kernel building13:52
IrcsomeBot<Zoth_Ommog> For android13:52
IrcsomeBot<Zoth_Ommog> Even then I only use the /home partition to do it13:53
IrcsomeBot<DarinMiller> Many build process use /tmp so may that be part of the issue.  Usually /tmp is cleared on reboot.13:54
IrcsomeBot<DarinMiller> try this sudo find /var/log -type f -size +1000M13:54
IrcsomeBot<DarinMiller> I want to ensure none of the log process ran wild...13:56
IrcsomeBot<Zoth_Ommog> Didn't work13:57
IrcsomeBot<DarinMiller> Nothing was returned or error reported?13:57
IrcsomeBot<Zoth_Ommog> Nope13:58
IrcsomeBot<DarinMiller> run the same command from root: sudo find / -type f -size +10000M14:00
IrcsomeBot<DarinMiller> Wait too many zeros:  sudo find / -type f -size +1000M14:01

IrcsomeBot<DarinMiller> ls -alh the last file on the list.14:03
IrcsomeBot<Zoth_Ommog> Nope14:03
IrcsomeBot<DarinMiller> ls -alh /sys/kernel/debug/dri/0/admgpu_vram14:07
lundrvsI am reading a tutorial for programming in C++. And I find this point:14:07
IrcsomeBot<DarinMiller> how big is that file14:07
lundrvs"Add "/usr/include/freetype2" when it is in Linux. (The path of freetype2 may be different, it depends on your system)."14:07
lundrvsdoes anyone know what is "freetype2"?14:08
IrcsomeBot<Zoth_Ommog> @DarinMiller, 4gb14:09
IrcsomeBot<Zoth_Ommog> Amazing14:09
lundrvsor how is it named in Kubuntu?14:09
IrcsomeBot<Zoth_Ommog> Will uninstalling amdgpu alleviate it a bit?14:09
IrcsomeBot<DarinMiller> I would try removing /sys/kernel/debug/dri/0/admgpu_vram14:13
IrcsomeBot<DarinMiller> then run sudo apt update and sudo apt full-upgrade14:13
IrcsomeBot<Zoth_Ommog> Is it safe though14:14
IrcsomeBot<Zoth_Ommog> I installed it from a amdgpu zip file14:14
IrcsomeBot<DarinMiller> 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.14:15
IrcsomeBot<DarinMiller> nm, bad advice, that file is not deleateable: https://askubuntu.com/questions/972624/how-to-delete-debug-files-in-sys-kernel-debug14:19
IrcsomeBot<Zoth_Ommog> Ah lawd14:21
IrcsomeBot<Zoth_Ommog> Amdgpu uninstall fixed it14:21
IrcsomeBot<DarinMiller> Very good. I still recommend increasing the size of your root partition so that you have a little more breathing room.14:24
IrcsomeBot<Zoth_Ommog> Yeah, I'll get a new HDD this weekend to give myself some space14:25

geniiThis is usually what it does when urnrar is not installed17:18
geniiunrar ...rather17:18
oerheksno thumbnails from archives is pretty logical ? https://itsfoss.com/how-to-run-cbr-files-in-ubuntu/17:20
