[opensuse] Leap 42.2 Feedback
by Aaron Digulla 07 Dec '16

07 Dec '16

Hi, I've upgraded to Leap 42.2 a week ago and I'd like to share my experiences. It was 90% successful but I have two big pain points: 3D and hibernate. Both features have degraded slowly over the past months (it started with Leap 41.1, 13.2 was very stable for years). Newer kernels tend to be less stable. 4.1 worked pretty good, 4.7 didn't work at all. I used "zypper dup" to upgrade my distribution from Leap 41.1 and that worked well, despite the fact that the wiki wasn't updated for Leap 42.2. But the instructions for 13.x -> 42.1 were easy enough to understand, so I could translate them myself. First boot worked, display manager failed. I had some trouble downloading the correct NVIDIA driver. I have a ASUS GTX 1050 Ti, so I needed 375.20. When I had that, the display manager (sddm?) started working. There were a couple of updates, so I installed those. I'm using KDE. Clicking on "Logout" did nothing. journalctl reported that sddm-greeter was crashing. I tried again, same result. Yesterday, I installed updates again and sddm-greeter refused to work afterwards. I had to reboot manually from the console. This sucks. From my point of view, sddm seems to be more of a problem than anything else. Not being able to do anything from the UI leaves me helpless and frustrated. I understand that Mesa updates replace important 3D libraries and sddm needs them but this piece of software is so important that it should fall back to something useful when it can't use 3D. That said, after updates, a lot of KDE software, chrome and chromium started to act up until I reinstalled the NVIDIA drivers. The error messages were mostly useless (that's what the KDE error reporter told me) or I didn't get any message at all. I'm not sure what less educated users would do in my situation. Not being able to reboot after installing security patches shouldn't happen. It makes me wonder whether I really need those patches. I also have a lot of graphics garbage on the screen after resume from hibernate to disk. That started with Leap 42.1 some time in September, I think. Window frames, Flash web content and desktop icon texts are most vulnerable. My guess is that the KDE 3D code is broken somehow but I don't know how to find out what is happening. Frustrating again. Also, when this happens, I can't disable 3D effects in systemsettings5 since that crashes immediately when I try to open the effects. During hibernate, I get messages on the (text) console that "BUG: sleeping function called from invalid context at ../kernel/locking/rwsem.c:21" Out of 20 attempts to hibernate, 4 fail to resume with the message: "ACPI: Hardware changed while hibernated, success doubtful" Something in the kernel must be broken since my hardware didn't change. And there is another "BUG: scheduling while atomic: systemd-sleep/.../..." Please let me know if I can provide more information to track down these bugs. Regards, -- Aaron "Optimizer" Digulla a.k.a.

[opensuse] rsync like function need
by Greg Freemyer 07 Dec '16

07 Dec '16

I should know this, but .. I'm moving hundreds of thousands of files from USB drives to a new destination drive. I've used rsync to make a copy of the files which is great. But I need to ensure all the files are exact copies. I don't think rsync has a "hash destination and report disagreements with source" feature. Is there a tool for doing that? fyi: I have a windows cmd line tool for doing this, but I'd rather work in linux.

[opensuse] copying rip'ed CD music to USB stick with vfat
by Per Jessen 07 Dec '16

07 Dec '16

I have a USB stick (thumbnail size) for the car, I rip CD's and copy them over. Every now and then, the copy will fail with error messages that appear to be related to the character sets and such: cp: cannot create directory ‘Pet Shop Boys - Discography: The Complete Singles Collection’: Invalid argument rsync: mkstemp "/var/run/media/per/BBC2-DF04/.06 - What Have I Done To Deserve This?.mp3.7myEiY" failed: Invalid argument (22) rsync: mkstemp "/var/run/media/per/BBC2-DF04/.18 - Was It Worth It?.mp3.Hbf1LV" failed: Invalid argument (22) cp: cannot create regular file ‘10 - Fughetta "In dich hab ich gehoffet, Herr".mp3’: Invalid argument Apparently '?', ':' and '"' are all causing a problem. I've googled it some and read a few pages about how to mount the usb stick with the right codepage and charset .... it's been so long since I've had to dabble with codepages and charsets .... Here is what I would like to do - pop in a CD, crank up k3b, rip the contents into a folder <name-of-cd>, copy that folder to the usb stick (already mounted). On my laptop, the USB is typically mounted like this: /dev/sdb1 on /var/run/media/per/BBC2-DF04 type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=100,fmask=0022,dmask=0077,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro) All suggestions and insight most welcome. -- Per Jessen, Zürich (0.8°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] troubleshooting 13.2 USB issues
by Greg Freemyer 07 Dec '16

07 Dec '16

I have a PC I use for USB work. Somehting like: mount /dev/sdb1 /mnt # mount the destination. cd /mnt dd if=/dev/sdc of=image-file.dd I've had it running with oS 13.1 for a while. I updated it to 13.2 recently and now it is extremely unreliable. Various HDD metadata queries are failing routinely (but not reliably). And often, when I start the dd (like) process, the kernel starts spitting out errors continuously. I'm forced to hold the power-off button to be able to interact with the laptop. This is a production machine (laptop) and I need that feature to be highly reliable, so I need to get it resolved fairly quickly. My thought is to treat 13.2 as a failed update, and go straight to Leap 42.1 now. Any recommendations pro/con that approach.

[opensuse] LVM / software raid / dynamic raid? For a backup server of stable data.
by Greg Freemyer 06 Dec '16

06 Dec '16

This email might be offtopic, not sure. I have a minimum of 10 TB of data I want to consolidate off of multiple USB drives to free them up. The data is almost exclusively static and rarely accessed, but I need to maintain it. I have 2 copies of this data in most cases currently, but it is spread around multiple USB3 drives. (I have dozens of them). The plan for now is just to consolidate one copy of the data. I bought a 10 TB SATA drive to hold a first big chunk. I expect it will get filled quickly as I start to consolidate my backup copies, so I want to be able to grow the volume holding the data by adding disks to the pool and extending the volume. I suspect I will also want to have more resiliency at some point. (ie. raid 0 => raid 5 => raid 6) If I truly had confidence in this storage pool I might eliminate both copies of the data that is on USB drives currently. But even with raid 6, I think I would worry about a total LVM or Volume crash Or even a user error! Even though I know LVM and MDraid somewhat, I don't know if is "dynamic" and "reliable" enough for what I want. And advice out there? Goals: - Create a fileserver that I can add drives to from time to time and grow it's capacity. Probably 10TB drives so I don't have too many spindles in the mix. When bigger drives become available, I'd prefer to use them, so being stuck will all the same size drives is a negative. - Performance is non-critical. I've used LTO-4 tapes to do this in the past, but I hope online is a better choice now. With LTO-4, once I had a new data set (typically 100GB - 2TB) I would make a backup with tape and put it away for the time I needed to ensure I still had it. (Often years). - Share the exported volumes with Windows PCs. (Not critical, but preferred) - have the ability to start the drive pool with a single drive and add to it over time - Allow the added drive to be either as SATA USB3.1 - Allow the Raid "protection level" to be adjusted for a given volume from time to time. === I was actually planning to do this with Windows and its "Storage Spaces" solution. I just this afternoon put a new 10TB drive in a windows PC and added it to the "Storage Space" (like LVM). But my reading says the "resilience level" of a volume has to be set at the time the volume is created. I can grow it later, but I can't change it from a raid 0, to a raid 1, to a raid 5, etc. Thanks Greg -- Greg Freemyer -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

In general everything works as expected with one exception: I have artefacts in context menus and application menues up to complete unreadable menues. Everything else isn't distorted at all. When switching off the compositor, the problems disappear. Switching from opengl 3.1 to 2.0 doesn't help, though. Is there any setting to improve menue rendering in this situation? Or some parameter for the modesetting module oder the nouveau driver? Thx and bye.

[opensuse] How to set VGA mode after boot, like bootloader does? (for 'kexec' consistency)
by L A Walsh 06 Dec '16

06 Dec '16

I found that it's the boot loader that sets the initial screen mode before the kernel is loaded. It is often set again during boot by programs that set the console keyboard and font -- and seems to be separate from the mode one is in during a graphical boot. I'm trying to figure out how to set that VGA mode from "userland" (running as root) just before jumping to a new kernel with kexec. If I don't, kexec starts the new kernel in a non-deterministic mode that displays mostly garbage on the screen up until the screen's mode is reset by console kbd+font progs. Alternatively -- I've also seen the screen go blank for the entire boot process until the system displays the login prompt. Does anyone know how to do set the VGA mode from userland so kexec will start in a known state? I don't think the method used in boot loaders would work, as I think they are making BIOS calls to detect and set modes... :-( Thanks MUCH!... linda -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Graphics errors with Leap 42.2 and Intel
by Bjoern Voigt 05 Dec '16

05 Dec '16

I had some strange graphics errors both in KDE Konsole and in Gnome Terminal after upgrade from Leap 42.1 to Leap 42.2. I had multiple cursors in one terminal windows, typing was invisible, but the output of commands showed up correctly. Also scrolling in one terminal moved text blocks on another overlapping terminal window. The effect was visible both with and without the KDE desktop effects. I use an Intel 4200U CPU with integrated graphics. The secondary graphics card (Nvidia 730M) was disabled with "bbswitch". After updating all X components from the X11:XOrg repository (zypper dup --from X11_XOrg) the problem is gone. Is this a known problem?
