There is a big difference I have seen. I know yesterday on a laptop. KDE live USB was a much faster boot than Windows from it's internal drive. Now the login is another issue. I find KDE login is slow on my older machines, slower than it used to be. FWIWdmes systemd-analyze Startup finished in 2.072s (kernel) + 14.811s (initrd) + 40.174s (userspace) = 57.059s AMD FX(tm)-8320 Eight-Core Processor Slower HDD' Another machine F24 Startup finished in 1min 10.623s (firmware) + 5.244s (loader) + 9.764s (kernel) + 35.582s (initrd) + 13.769s (userspace) = 2min 14.982s Intel(R) Core(TM) i7-5930K CPU @ 3.50GHz ssd HDD This machine motherboard is slow to boot as it does some checks when powering on and I don't know if that is part of the startup timing. I will have to check with a watch one of these days. Both machines have bios passwords and system encryption passwords. From what I have heard, from cold boot, Windows 10 is slower on this machine and runs slower. Still, the time I press enter to login till KDE desktop is ready to use seems to be slower.

service menu only when 2 files are selected

i created the servicemenu below because it's annoying that "kompare" don't remember the last folder when chose files to compare is there some way to limit it only to appear when *exactly* 2 files are selected (yes ~/.local/share/kservices5 is a symlink to ~/.kde/share/kde4/services/ServiceMenus/ for handle the unholy mix of KDE4/KDE5 stuff and i want my ark-contextmenues back as well as useable kdesvn options in KDE5) [harry@srv-rhsoft:~]$ cat /home/harry/.kde/share/kde4/services/ServiceMenus/kompare.desktop [Desktop Entry] Type=Service Encoding=UTF-8 ServiceTypes=KonqPopupMenu/Plugin,text/*,application/javascript,application/php,application/rss+xml,application/x-httpd-php,application/x-httpd-php-source,application/x-javascript,application/x-perl,application/x-php,application/x-sh,application/x-python,application/x-shellscript,application/xhtml+xml,application/xml+rss,application/xml X-KDE-Priority=TopLevel Actions=KompareFiles [Desktop Action KompareFiles] Name=Compare Files Name[de]=Dateien vergleichen Icon=kompare Exec=kompare %U

Kontact hangs in Fedora 26
by José Abílio Matos 08 Apr '17

08 Apr '17

Hi, I have upgraded this week to Fedora 26 (post alpha). The only issue that I have is that kontact hangs when launched. The cpu time goes to 100% for kontact. This is a minor annoyance since kmail, the component that I am mostly interested in, works standalone with no apparent issue. This is the only difference that I get from F25 either in KDE/plasma or in any other component. :-) -- José Abílio

KDE in Rawhide: things are...bigger?
by Adam Williamson 06 Apr '17

06 Apr '17

Not quite sure how more specifically to describe this, but recently the Rawhide KDE tests in openQA started failing because a couple of interface elements are, well...bigger. The openQA 'needle' for the KDE login screen matches on the generic user avatar that's shown on that screen. In the last couple of Rawhide composes it looks basically the same as before, only...bigger. Compare today's F26 compose: https://openqa.fedoraproject.org/tests/76678#step/_graphical_wait_login/3 and today's Rawhide compose: https://openqa.fedoraproject.org/tests/76716#step/_graphical_wait_login/3 (It's easiest to compare by changing the 'Candidate needle' dropdown to 'None'). The 'shadow in a circle' thing looks basically the same, just... *bigger*, in Rawhide. Similarly with the Fedora logo kicker button on the desktop. F26: https://openqa.fedoraproject.org/tests/76678#step/_graphical_wait_login/6 Rawhide: https://openqa.fedoraproject.org/tests/76716#step/_graphical_wait_login/12 the kicker launcher icon is the Fedora logo in both cases, but in Rawhide, it's just...bigger. I can easily adjust the openQA needles to match the changes, I'm just curious, really, whether this is an intentional change or not. Anyone? -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net

F26 Konsole 16.12.3 lost scrollbar buttons

Scrollbar buttons disappeared, like the idiotic GTK3 defaults. How does one go about getting them back? -- "The wise are known for their understanding, and pleasant words are persuasive."

Ian, your suggestion to type in "kstart kwin --replace" worked if I had a konsole open. Anything I typed was associated with the last application open. Robin
