[01:25] 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] I have this problem in : dragonplayer, vlc, kate, virtualbox, chrome [01:26] Which video card? [01:26] nvidia - sigh [01:27] And driver version? [01:27] 440 [01:28] nvidia-settings shows 400.100 [01:28] Geforce GTX1050TI [01:28] What render mode in System Settings -> Disp. Config. -> Compositor -> Rendering backend [01:29] opengl 3.1 (with message that it caused a crash in the past) [01:31] 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] 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] reenabled and rebooting after your response [01:33] here is a screenshot of a window with messed up content : https://pasteboard.co/JoZIeq8.png [01:44] 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] it blocks me as I need virtualbox to start a VM but because of the paint problems VBox is unusable [01:44] Compositing enabled? [01:45] enabled yes [01:45] disable ? [01:45] No [01:45] setup is dual display FWIW [01:46] 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 [01:47] If you unplug one display, does the problem go away? [01:47] ok I will upgrade to the 450 ... I presume the upgrade would uninstall the 440 ? [01:49] if I disable my second monitor the problem goes away !!!!!!!!!!!!!!!!!!!!!!! [01:49] (disable from settings ) [01:49] and also video starts to play (before nor vlc nor dragonplayer were able to play video ) [01:51] 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 [01:52] Under Nvidia Settings -> X server XVideo Settings try changing the default sync device... [01:52] ^^^ totally guessing here ^^^ [01:53] So does everything work on either monitor as long a the other monitor is disabled? [01:53] only tested on the 4K monitor (disable the FHD one). sync does not seem to work [01:54] I have not logged out when changing sync. should I ? [01:54] Most of the NVidia settings do not require loggout... [01:56] Under NVS -> OpenGL Settings have you tried toggling Allow Flipping or any of those options? [01:57] Note, the hover help often specifies if the setting applies immediately. [01:57] sync to vblank is on, flipping off, use conformant texture mapping on, [01:58] image settings : quality [02:00] 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] ok ... will try and logout [02:03] 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 [02:05] Oh yes! Use Font to change the size of everything using X. Wayland scaling is much better, but very difficult to enable using NVidia. [02:06] The reason I run my 2k scaled to 4k is that sizes font and windows size match across monitors. [02:07] However, scaling 1080p to 4k is a bit blocky for my preference (2K to 4k is very useable). [02:08] 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' [02:09] Yes, correct. Only under Wayland does the per display scaling work. [02:10] I do not mind using wayland but is it already operational for KDE ? I read that there were still open issues ... [02:10] logging out again [02:11] Not until Qt 15.xxx is available will Wayland run using NVidia and proprietary drivers.

I have seen 3 different 20.04 installs where the log files hit 12GB or larger. [13:19] How? [13:20] I can only access terminal [13:22] how big is the syslog file (ls -alh /var/log/syslog ) [13:24] 316k [13:25] It's the apt/archive that is chock full [13:30] have you already ran sudo apt autoremove ? [13:31] Yes [13:31] autoclean too [13:31] clean did nothing at all [13:38] If you run df -lh, how big is your root directory? === skeer__ is now known as skeer [13:41] (Photo, 668x500) https://irc-attachments.kde.org/0XDbOwNp/file_35516.jpg [13:42] oh crap, 14G is a little small these days for a root directory. [13:42] Really? Dammit [13:43] Devs assume everyone has lot of hd space and packages are starting to bloat. [13:43] I haven't had time to switch /home to the hdd [13:44] What's the recommended size nowadays [13:50] 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] Do you run any VM's? [13:52] Nope [13:52] The most I do is kernel building [13:52] For android [13:53] Even then I only use the /home partition to do it [13:54] Many build process use /tmp so may that be part of the issue. Usually /tmp is cleared on reboot. [13:54] try this sudo find /var/log -type f -size +1000M [13:56] I want to ensure none of the log process ran wild... [13:57] Didn't work [13:57] Nothing was returned or error reported? [13:58] Nope [14:00] run the same command from root: sudo find / -type f -size +10000M [14:01] Wait too many zeros: sudo find / -type f -size +1000M [14:02] (Photo, 668x500) https://irc-attachments.kde.org/4LEeLQpZ/file_35519.jpg [14:03] ls -alh the last file on the list. [14:03] Nope [14:07] ls -alh /sys/kernel/debug/dri/0/admgpu_vram [14:07] I am reading a tutorial for programming in C++. And I find this point: [14:07] how big is that file [14:07] "Add "/usr/include/freetype2" when it is in Linux. (The path of freetype2 may be different, it depends on your system)." [14:08] does anyone know what is "freetype2"? [14:09] @DarinMiller, 4gb [14:09] Amazing [14:09] or how is it named in Kubuntu? [14:09] Will uninstalling amdgpu alleviate it a bit? [14:13] I would try removing /sys/kernel/debug/dri/0/admgpu_vram [14:13] then run sudo apt update and sudo apt full-upgrade [14:14] Is it safe though [14:14] I installed it from a amdgpu zip file [14:15] 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. [14:19] nm, bad advice, that file is not deleateable: https://askubuntu.com/questions/972624/how-to-delete-debug-files-in-sys-kernel-debug [14:21] Ah lawd [14:21] Amdgpu uninstall fixed it [14:24] Very good. I still recommend increasing the size of your root partition so that you have a little more breathing room.

[16:18] I don't mean the original, but the fanmade sequel [16:21] nevermind, just found a solution [16:21] The original ran fine in real mode under dosbox. Dunno about the sequels [16:22] @resophokles_, Please tell... [16:30] well there is a linux version for the sequel [16:31] http://www.mckracken.net/cms/directorscut.html === Lord_of_Life_ is now known as Lord_of_Life [17:05] (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] This is usually what it does when urnrar is not installed [17:18] unrar ...rather [17:20] no thumbnails from archives is pretty logical ? https://itsfoss.com/how-to-run-cbr-files-in-ubuntu/ [18:39] @genii, Oh thanks a lot!
