After the update it seems that my Plasma is broken. The application drawer/toolbar doesn’t work at all - it’s neither interactable nor it actualises status (e.g. clock). Actions like Alt+Space (KRunner?) or changing volume work after a huge delay (like 1 minute?). MangoHud and switching apps with Alt+Tab works. Switching desktops/workspaces doesn’t. Games work fine.
After running journalctl -p err -b I get:
kernel: nvidia-gpu 0000:06:00.3: i2c timeout error e0000000
kernel: ucsi_ccg 0-0008: i2c_transfer failed -110
kernel: ucsi_ccg 0-0008: ucsi_ccg_init failed - -110
systemd-coredump[1788]: Process 1334 (baloo_file) of user 1000 dumped core.
I have no idea what to do next.
I have nvidia 460 driver and tried on 5.10 and 5.4 kernels.
I’m not sure if its graphics card issue but @Fabbyasked me to post it here for more probing.
EDIT: I’ve also just noticed a new thing - some kind of loading started:
then I got a notification from Plasma: “Error Malformed Url”. And everything apart from KRunner started to work normally(?). That’s however after multiple reboots and using the system for ~10 hours.
Does this also happen in a newly created user? (E.G. jango2)
Can you also post an inxi --admin --verbosity=7 --filter --no-host --width which would be the minimum required information we need to continue looking into this… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
Ok so this is very weird for me. I created a new user, everything worked fine. Now I rebooted into my account and everything works fine, despite it didn’t work after multiple reboots I had before.
The only thing I did today was downloading updated kernel 5.10 related files - however after rebooting it didn’t work. Should I close this thread? I’m so confused.
I still have this nvidia timeout error in log.
For a machine with 16GB of RAM, create the following file:
/etc/sysctl.d/30-swap_usage.conf
and add the following into it:
# janquo: 2021-02-11: change "swappiness" from default 60 to 10:
# Theoretically, only swap when RAM usage reaches around 80 or 90 percent
vm.swappiness = 10
# janquo: 2021-02-11: Lower vm.vfs_cache_pressure to 75%
# (once cached, probably not immediately needed any more)
#
# This percentage value controls the tendency of the kernel to reclaim
# the memory which is used for caching of directory and inode objects.
#
# At the default value of vfs_cache_pressure=100 the kernel will attempt to
# reclaim dentries and inodes at a "fair" rate with respect to pagecache and
# swapcache reclaim. Decreasing vfs_cache_pressure causes the kernel to prefer
# to retain dentry and inode caches.
vm.vfs_cache_pressure = 75
In a nutshell: the system will swap out later (only at 90% memory utilisation, and once swapped out, not try to swap in immediately as memory becomes available… (snappier performance under high load)
