But I'm having trouble getting it to consistently occur. When it occurred in the same session I also saw popups concerning a kwin reset. So perhaps it is linked to compositor or window management issues. Or perhaps due to me switching to a text console to run htop. I now have a power monitor on the PC's wallplug so that when it happens I will return to see the power consumption at 125 W instead of the expected 65 W. Have you tried getting the locker to do less by setting a plain colour and or turning off the clock? When I set a plain colour I thought I'd fixed it, but it's more likely due to me logging out and logging in which would have reset kwin and the compositor. At the moment if I run the locker with no arguments its working fine with any settings I care to try: /usr/lib64/libexec/kscreenlocker_greet I wonder if there was some junk in a config file somewhere that all my playing has cleared. I noted you other message about it being a known fixed bug that may not actually be fixed. As the bug seems to be related to openGL, I might try the Display and Monitor - Compositor - Rendering backend options to see if that shakes things up a bit? That might cause more trouble I suppose. I'm totally grasping at straws here I'm afraid. I'm willing to try other experiments if it would help. Sorry to be the source of false hope.

[opensuse] intel opengl
by jdd＠dodin.org 24 Feb '20

24 Feb '20

Hello, I want to use a proprietary software (DaVinci Resolve). My ASUS N550JK is an optimus computer, but I never could make bumblebee work more than 10 mn long (during these minutes, resolve worked 5x faster than kdenlive, the reason why I would like to use it). Resolve works on a much less powerful computer with intel graphics and no optimus. On the ASUS, it ask for "an openCL interface". As far As I understand, Mesa openCL (and lib openCL) is installed. Is it possible to to hide completely the nvidia video part? Is there a chance intel driver can provide openCL? Note: I can't make bumblebee work right now, neither in openSUSE nor in ubuntu or the native resolve distro of choice centos, so using it is not a reasonable choice for the moment thanks jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Tumbleweed - kde screenlocker gobbling up a CPU ?

[opensuse] Obsolete entry in fstab stalls booting
by zb4ng 22 Feb '20

22 Feb '20

Please note, that the problem at hand is already solved, but the underlying issue gets in my way from time to time, so I wanted to tell (or rant 😉) about it. Two days ago, I wasn't able to boot my system (LEAP 15.1): X-Server didn't start and I could only log into maintenance mode with no network either. First, I suspected a botched update, but the kernel-firmware was updated a couple of days before and I had successfully booted in the mean time. So, I was dumbfounded, but then I remembered to look into /etc/fstab and found an entry of a USB drive that I had plugged in and removed. I deleted said entry and LEAP booted just fine. My point is: maybe the maintainers could help to avoid this situation: Please, don't break the boot process if some malfunctioning but unimportant entry in fstab doesn't work! Or at least, make it easier for the user to find out what is going wrong. I had similar issues multiple times over the past years and sometimes it took me quite a time to figure them out.

[opensuse] TW observations
by Per Jessen 21 Feb '20

21 Feb '20

I have not installed a new Tumbleweed in years. Today I was prep'ing a new machine for our datacenter console, and decided I might as well use Tumbleweed. In yast ncurses, I was surprised to see - a) to change to wicked I have to tab into the option, it is not available with keyboard shortcuts under Change->Network Config. b) that predictable interface names were used by default (easily changed, I know). c) at the end of installation, a pop-up window with no timer ? That one meant a bit more exercise for me - I saw the installation drawing to a close, so I left my office to walk to the datacentre and see the box boot-up. -- Per Jessen, Zürich (8.2°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] What process/program handles file system use?
by Istvan Gabor 20 Feb '20

20 Feb '20

Hello: In the thread of my previous question on "usable free space on an ext4 file system" I wrote that I could not fill the available free space with one big file. In openSUSE 13.1 I can not copy one big file to fill the available free space. I found that in openSUSE Leap 15.1 I can copy the same file to fill the available space, using the very same partition. When I want to copy the file the system says there is no space left on the device. Some file is copied partially. In this case df reports that the available space is 0. If I umount the file system and mount it again, df reports that the available space is 55K. I find it srange. Maybe it is a silly question, but I would like to know what process or program handles file systems and their use (used space, available space). Is it the kernel or mount program or somethging else?

[opensuse] creating symlinks for all files in directory recursively in specified directory
by Istvan Gabor 20 Feb '20

20 Feb '20

Hello: I tried to summarize in the subject what I'd like to do: I want to create symlinks for all the files within a folder recursively with the symlinks to be in one directory. For example: Source dir: source/dir1/a/file1 source/dir1/a/file2 source/dir1/a/file3 source/dir1/b/file4 source/dir1/b/file5 source/dir1/b/file6 source/file7 The target should be: target/file1 -> source/dir1/a/file1 target/file2 -> source/dir1/a/file2 target/file3 -> source/dir1/a/file3 target/file4 -> source/dir1/b/file4 target/file5 -> source/dir1/b/file5 target/file6 -> source/dir1/b/file6 target/file7 -> source/file7 How could do it?

[opensuse] browser and passwords and RSA, oh my.
by Roger Oberholtzer 20 Feb '20

20 Feb '20

I have a very unusual situation. I am trying to log in to a web site (https://www.zf-laser.com if you are curious) from either Firefox (72.0.2) or Chrome (79.0.3945.130) on Tumbleweed. I enter the password, but it is not accepted. Both browsers change the password I have entered into a long string that starts with "rsa:". I am guessing this is what they send. And, when Firefox offers to keep the password, I see that it is this same altered string, not the one I entered. I can log in to other sites (e.g. OBS). But not this one. I have no idea what is happening. Especially since both browsers do the same thing. Any ideas? A Google search did not seem to me to show anything related to this. Just stuff generally about RSA and passwords in browsers. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] checking if patches for spectre, meltdown etc are applied or not ?
by Per Jessen 19 Feb '20

19 Feb '20

We have a customer for whom we manage a number of boxes - they are used for some hpc app, molecular modelling or some such, I'm not sure. This morning I was asked if these systems have the mitigation patches for Spectre, Meltdown etc applied. Apparently these patches have measureable performance impact - the next question was: if they are applied, can we have them un-applied?
