Screen sharing: global solution for Wayland that works for all apps
by Raman Gupta 07 Jan '22

07 Jan '22

I'm finally switching over to Wayland as my daily driver. However, I'm still finding big problems with screen sharing in general. I'm on KDE/Plasma. Many apps that are supposed to support screen sharing on Wayland -- Electron-based apps, Chromium, OBS, proprietary apps like Zoom etc. either completely don't work, or work but only partially. For example, Chrome can share X11 windows but not Wayland windows, and cannot share screens at all (the option is available, but the screens are just black). OBS doesn't work with Pipewire+Wireplumber either, though it does seem to be able to capture windows that are running under XWayland. Some very nice and useful apps e.g. Pop simply output: "we don't support Wayland, switch to X11". As long as it is up to each app to develop their own solutions for Wayland this situation is likely to only change in a decade or so, if even then. Are there any tech initiatives on the go -- maybe at the compositor level? -- to have Wayland screen sharing work essentially transparently to apps that have already got screen sharing working for X11? I'm fine with a global setting that says "I don't care about screen sharing security" -- that's essentially what I'm doing by changing my desktop back to X11 anyway.

support term for Fedora 34
by Anil Felipe Duggirala 06 Jan '22

06 Jan '22

I will ask this question here since I didn't understand the explanations I found elsewhere. Until when will Fedora 34 be supported? Is it highly recommended that I upgrade to Fedora 35 at this point? thank you, Anil F

SELinux is preventing mktemp from using the dac_read_search capability.
by Robert Moskowitz 06 Jan '22

06 Jan '22

I keep getting these errors. I got them back with F32 and Xfce, and now with F35 and Xfce. I asked on the SElinux list, but no one seems to be home. Here is the full detail; it looks like it may be logwatch causing the problem. What do I do to fix this? =============== SELinux is preventing mktemp from using the dac_read_search capability. ***** Plugin dac_override (91.4 confidence) suggests ********************** If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system Then turn on full auditing to get path information about the offending file and generate the error again. Do Turn on full auditing # auditctl -w /etc/shadow -p w Try to recreate AVC. Then execute # ausearch -m avc -ts recent If you see PATH record check ownership/permissions on file, and fix it, otherwise report as a bugzilla. ***** Plugin catchall (9.59 confidence) suggests ************************** If you believe that mktemp should have the dac_read_search capability by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'mktemp' --raw | audit2allow -M my-mktemp # semodule -X 300 -i my-mktemp.pp Additional Information: Source Context system_u:system_r:logwatch_mail_t:s0-s0:c0.c1023 Target Context system_u:system_r:logwatch_mail_t:s0-s0:c0.c1023 Target Objects Unknown [ capability ] Source mktemp Source Path mktemp Port <Unknown> Host lx140e.htt-consult.com Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-35.7-1.fc35.noarch Local Policy RPM selinux-policy-targeted-35.7-1.fc35.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name lx140e.htt-consult.com Platform Linux lx140e.htt-consult.com 5.15.11-200.fc35.x86_64 #1 SMP Wed Dec 22 15:41:11 UTC 2021 x86_64 x86_64 Alert Count 13912 First Seen 2021-11-15 03:27:05 EST Last Seen 2022-01-02 03:09:16 EST Local ID 2ef8a1a9-ddf5-42cc-b5dc-c08354265cc8 Raw Audit Messages type=AVC msg=audit(1641110956.728:1612): avc: denied { dac_read_search } for pid=24078 comm="dotlockfile" capability=2 scontext=system_u:system_r:logwatch_mail_t:s0-s0:c0.c1023 tcontext=system_u:system_r:logwatch_mail_t:s0-s0:c0.c1023 tclass=capability permissive=0 Hash: mktemp,logwatch_mail_t,logwatch_mail_t,capability,dac_read_search _______________________________________________ selinux mailing list -- selinux(a)lists.fedoraproject.org To unsubscribe send an email to selinux-leave(a)lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/selinux@lists.fedoraproject.o… Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure

Next notebook
by Robert Moskowitz 05 Jan '22

05 Jan '22

I am currently using Lenovo Thinkpad x140e with 4Gb mem. I have 3, 2 for Fedora and 1 for Win10. The Fedora ones have been upgraded with 500Gb SSD drives. I like Thinkpads for the eraser head pointer device. and x140e for the 12" monitor format (works well in airplane seats). But what next to replace the circa 2013 device? I have tried to figure this out from the Lenovo site. It was easy figuring out going from the x120e (got 4 of those still) to the x140e, but I don't see the upgrade path from the x140e. Anyone here familiar with Lenovo to help me? I figure scouting around and having it ready for the F36 install. thanks

F35 HP-toolbox in Xfce
by Robert Moskowitz 05 Jan '22

05 Jan '22

I notice that when I use HP-toolbox (normally to get to scanning from my network attached printer) that when I close the toobox an icon that looks like a lightbulb stays on the system tray. It has a 'quit' option when I right click on it, but it never seems to quit. It just stays there, reporting anything I send to my printer. Seems like a bug? thanks

I have defeated Wayland!
by Tom Horsley 05 Jan '22

05 Jan '22

https://tomhorsley.com/hardware/mouse-tailor/mouse-tailor.html My latest silly project adds all the mouse settings to microcode outside of the operating system so my trackball can be useful when I'm forced to use Wayland (which seems to have utterly discarded any useful mouse settings once available under X11).
