[Testing Update] 2019-05-29 - Kernels, XFCE, Deepin, Mesa, Nvidia, KDE-Dev

I finally fiexed the issue with zfs-import-cache.service.

I had to remove and readd the cachefile option to the filesystem:

zpool set cachefile=none zstore
zpool set cachefile=/etc/zfs/zpool.cache zstore

Now zfs-import-cache.service works out of the box.


Another testing update is already up.
It would be nice if you updated the known issues with the zfs issue and workaround to both.
Just saying... :man_shrugging:

Please check the upstream bugtracker and post a new issue if needed.

for Xfce & Drivers Nvidia ( but should also be checked for others )
i have on Idle Xorg cpu running 4% to 6% or 8% under top/htop

Oh yeah, I've just noticed that Krita 4.2 also breaks global menu compatibility.
This KDE app has always been very odd.


Nvidia 430.14 broke mpv hardware decoding.

vo=gpu (the default mode) with hwdec=yes results in Segmentation fault (core dumped). hwdec=cuda and copy-back modes also segfaults.

dmesg output:

[  702.543306] mpv[2262]: segfault at e ip 00007f0b65b0d0c0 sp 00007ffdc802e4e0 error 4 in libnvcuvid.so.430.14[7f0b65acc000+312000]

vo=vdpau works with hwdec=yes, but there is now stutter in 60fps videos. It can be fixed by turning compositor off (it does not seem to matter which compositor is used, tested with xfwm4 and compton glx).

vo=vdpau 60fps stutter can also be fixed (mostly) with these additional mpv options:


vo=vdpau and hwdec=cuda still segfaults.

It depends if prime or bumblebee is used. Non-glnvd libs are however broken in 430.

this will not be easy

" Given the recent work on glxvnd in Xorg, can we assume a native solution for Optimus is in the pipeline? With the dynamic power switching problem being already solved natively in the kernel for newer Optimus hardware, if glxvnd/glvnd can solve the bringing problem then we won't need bumblebee and primus anymore with new hardware and a recent software stack. We can keep them for the legacy driver series.

I similar problems on Arch Linux but only the DisplayPort output is affected. HDMI output runs perfectly.

I have returned to 390xx drivers.


on nvidia notes
Support for non-GLVND OpenGL and EGL libraries on Linux
The release 430 series will be the last to support installing Linux OpenGL and EGL client libraries that do not use the GL Vendor Neutral Dispatch (GLVND) loader library.

on notes
"The first post has been updated to note that support for Linux non-GLVND OpenGL and EGL client libraries will be removed in a future release."

4 version drivers , depreciation as they want that not always indicated on version , and breaks dance for optimus / primus .... ( laptop )

Opera menu bug looks like a long term Chromium issue I reported years ago about popup descriptions being screwed up too. Try with hardware acceleration turned off

Thanks. This fixed the bug.
Strange thing is that I see this bug first time. It appears after 05/29 update wich included Opera minor update.

Seems there is an issue with new version of network-manager-applet 1.8.22-1.

Passwords for VPN connections don't seem to be stored when "Store the password only for this user" is selected. When entering the password in the configuration and pressing save, next time you open settings again, the password field is empty. Also it'll ask you for the password on connecting...

downgrading to 1.8.21dev+3+gb4c365b1 fixes the problem.

btw. when working in a single user environment one can choose "Store the password for all users". That still works.

reported it here: https://gitlab.gnome.org/GNOME/network-manager-applet/issues/59

Seems to be a regression. Will check the code.

I do not understand how GLVND interacts with vdpau and cuda. I am not using prime or bumblebee however.

Maybe this bug report is related to the mpv hwdec segfaults?

I don't know how to downgrade Nvidia without rolling back my entire system using Timeshift however... :panda_face:

Edit: OK downgrading nvidia and all kernels worked.

Seems we have to revert to the previous driver as it seems.

Always point to the exact git-commit we are using:

It would be nice if you updated the known issues

As I use ZFS I might need a reminder when eventually updating to 0.8 in stable, so I've put a brief note in the wiki-posts for this update and May 30th. Hope mbod doesn't mind.
