[opensuse] Another annoying "feature" - 15.1 & KDE
by James Knott 22 Aug '19

22 Aug '19

There seems to be a bug with KDE on 15.1. Frequently, when I click on an open item on the task bar, the list of windows for that app no longer appears. However, if I just hover over it, then the windows are listed in a horizontal row. Is there anyway to fix this? At the moment, I have to log out & in. tnx jk -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Epson Inkjet Printer can't connect
by Doug McGarrett 13 Aug '19

13 Aug '19

Re: Tumbleweed: I have an Epson WP-4530 all-in-one printer/copier/scanner. The Driver is available in /usr/etcetera, and Yast claims to have installed it, and if I try to print something, the Epson is shown as a choice, but nothing happens. If I try to use XSane, a message tells me it can't find a device. Meanwhile, an HP LaserJet Pro is found and prints perfectly. But it can't scan or print in color. I've gotten used to Tumbleweed and I like it, but why won't it print? All help appreciated! --doug -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Compressed filesystems?
by Carlos E. R. 06 Aug '19

06 Aug '19

Hi, What filesystems do we have with transparent compression? Read/write, of course. I intend to create a compressed backup external disk (Leap 15.0) I know of btrfs and zfs. zfs is not supported officially on openSUSE, that's a con. I read on some sites not to use zfs on single drives (<https://www.ixsystems.com/community/threads/single-drive-zfs.35515/#post-21…>) «Well, the CTO of iXsystems said something like "single disk ZFS is so pointless it's actually worse than not using ZFS". Technically you can do deduplication and compression. But there is no protection from corruption since there is no redundancy. So any error can be detected, but cannot be corrected. This sounds like an acceptable compromise, but its actually not. The reason its not is that ZFS' metadata cannot be allowed to be corrupted. If it is it is likely the zpool will be impossible to mount (and will probably crash the system once the corruption is found). So a couple of bad sectors in the right place will mean that all data on the zpool will be lost. Not some, all. Also there's no ZFS recovery tools, so you cannot recover any data on the drives. You cannot use the standard recovery tools that are designed for NTFS, FAT32, etc either. They don't work correctly.» Other alternatives? btrfs seems to support it well. <https://btrfs.wiki.kernel.org/index.php/Compression> Then, what compression method to use? Default is zlib, says the wiki. «There's a speed/ratio trade-off: ZLIB -- slower, higher compression ratio (uses zlib level 3 setting, you can see the zlib level difference between 1 and 6 in zlib sources). LZO -- faster compression and decompression than zlib, worse compression ratio, designed to be fast ZSTD -- (since v4.14) compression comparable to zlib with higher compression/decompression speeds and different ratio levels (details) The differences depend on the actual data set and cannot be expressed by a single number or recommendation. Do your own benchmarks. LZO seems to give satisfying results for general use.» That seems to point to ZSTD. The wiki says there are 15 compression levels with ZSTD, but does not say which is the default or describe the expectations for each level. Points to a "details" link. Maybe level 1 would do. I do not want really high compression ratio, I prefer speed because backups are large. And things like email compress very well, anyway. Ideas? -- Cheers / Saludos, Carlos E. R.

[opensuse] libreoffice LibreLogo macro bug
by Dave Howorth 06 Aug '19

06 Aug '19

There's apparently a bug in LO that can run arbitrary code. https://www.theregister.co.uk/2019/07/30/libreoffice_macro_virus/ Does anybody know whether this has been or will be patched for Leap 15.0 (LO 6.1.5.2)/ i.e. an openSUSE back patch since LO aren't fixing AIUI. LibreLogo appears to be part of the libreoffice-pyuno package. Is there any way to disable it, or just remove the /usr/lib64/libreoffice/share/Scripts/python/LibreLogo directory?

[opensuse] Clone disk
by Roger Oberholtzer 02 Aug '19

02 Aug '19

I have a user (openSUSE 12.3 - I know...) that wants to clone the root disk. In fact, long ago, they did this. But apparently both they and I have forgotten exactly what we did... The disk copy went ok. dd the entire thing from one disk to another of the same type. We always mount by_id since there may be multiple disks. So, after the dd, one needs to mount the new disk and edit /etc/fstab with the new disk's ID. This has been done. The boot seems to then be looking for the correct disk. However, the boot does not happen. It just hangs. The kernel command line is the only thing printed. I do not have the disk in my possession (it's on a different continent). So, before I tell them to send it to me, I just want to be sure that I have not missed another step. Could there be a need to remake the initial ram disk? Is the disk id in there as well? If one has to do mkinitrd, how can one do that on a mounted disk (not the system's root disk)? Or maybe it is something else? -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Trying to create a compressed (and encrypted) btrfs filesystem
by Carlos E. R. 01 Aug '19

01 Aug '19

Leap 15.0 /etc/fstab: /dev/mapper/cr_my_book_tlcntr /mnt/BookTelcontar btrfs lazytime,compress=zlib:1 1 3 This is per instructions on the wiki (and man): <https://btrfs.wiki.kernel.org/index.php/Compression> But yields error: Isengard:~ # mount -v /mnt/BookTelcontar/ mount: /mnt/BookTelcontar: wrong fs type, bad option, bad superblock on /dev/mapper/cr_my_book_tlcntr, missing codepage or helper program, or other error. I have to use: /dev/mapper/cr_my_book_tlcntr /mnt/BookTelcontar btrfs lazytime,compress 1 3 which yields: mount: /dev/mapper/cr_my_book_tlcntr on /mnt/BookTelcontar type btrfs (rw,relatime,lazytime,compress=zlib,space_cache,subvolid=5,subvol=/) Is this a bug? Is the syntax different? man: compress, compress=type, compress-force, compress-force=type (default: off) Control BTRFS file data compression. Type may be specified as zlib, lzo, zstd or no (for no compression, used for remounting). If no type is specified, zlib is used. If compress-force is specified, then compression will always be attempted, but the data may end up uncompressed if the compression would make them larger. Otherwise some simple heuristics are applied to detect an incompressible file. If the first blocks written to a file are not compressible, the whole file is permanently marked to skip compression. As this is too simple, the compress-force is a workaround that will compress most of the files at the cost of some wasted CPU cycles on failed attempts. The heuristics of compress will improve in the future so this will not be necessary. Note If compression is enabled, nodatacow and nodatasum are disabled. -- Cheers / Saludos, Carlos E. R.

[opensuse] email weirdness
by Dave Howorth 31 Jul '19

31 Jul '19

I just received a mail delivery failure notice. It was to rschweikert(a)suse.com which is not somebody I ever remembering addressing an email to, but is somebody who I have seen on this email list in the past. What I found a bit concerning is that the notice included many statements like: Received: from INET-RELAY2-MTA by relay2.provo.novell.com with Novell_GroupWise Received: from M9W0068.microfocus.com (m9w0068.houston.softwaregrp.net I thought SUSE was now independent? -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

Running Leap 15.1-1 and mate-desktop-1.22.1-lp151.1.2.x86_64 When I iconify an app, it no longer has an icon on the task bar, so I am not able to re-display the running app. Any info on how to solve this problem? -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org
