The latest version of QT5 on Fedora 27 – qt5-qtbase-5.9.6-1.fc27.x86_64 – produces a very annoying display problem in KDE’s Dolphin file manager, where the window does not resize/reformat correctly, leaving large blank areas at each side: This has been identified as a QT5 bug/regression, and a patch is available, at https://codereview.qt-project.org/#/c/233482/ I have applied this, and Dolphin … Continue reading →
Updated to the latest Plasma Desktop, on one of my systems (Fedora 23, x86_64), and found that the ‘Favorites’ had all vanished, apart for xterm.. My other x86_64 system updated OK, with all the ‘Favorites’ intact.. Rather than hunt down all the apps and ‘add to favorites’ for each one, I found the old Favorites again, as … Continue reading →
Fedora 20 – KDE Desktop on ODROID U3 Found a suitable source tree for (old!) kernel 3.8.13.16: git clone -b odroid-3.8.y –single-branch https://github.com/hardkernel/linux – which compiled on the device itself with no problems – the old-fashioned way (# make zImage, etc..) and installed and ran without problems: Fedora release 20 (Heisenbug) Kernel 3.8.13.16 on an armv7l (ttySAC1) … Continue reading →

I had tried all the ‘patched’ NVIDIA drivers, and found that the ‘old’ 310.51 driver compiled OK, but didn’t work correctly … Continue reading →
SmartDeblur has received some exposure in the mainstream press recently, and as I do a lot of digital restoration of old slides and negatives, I wanted to get it to run on Linux, as well. Should be no problem, as the app is written in QT4.. So.. Download the source from GitHub: https://github.com/Y-Vladimir/SmartDeblur/downloads Then unpack the tarfile, … Continue reading →

I now have an Android so-called smart phone, and simply want to sync my calendar with my desktop (KDE 4.9.2).. This … Continue reading →
So, the problem can be summarised as follows: Login using ‘graphical boot’ (runlevel 5) and KDM – everything works correctly. Login using ‘multi-user boot’ (runlevel 3) and then use # startx to run KDE – USB disk mounts fail with “… Not Authorized” I use a non-graphical login (runlevel 3) and then run # startx, as this … Continue reading →
After recently upgrading from Fedora 16 to 17, I found that USB disk mounts in KDE were failing: Could not mount the following device An unspecified error has occurred Not Authorized I finally found a workaround at http://www.suurmeijer.net, and I have slightly modified it: Edit /usr/share/polkit-1/actions/org.freedesktop.udisks.policy as follows: <action id=”org.freedesktop.udisks.filesystem-mount”> <description>Mount a device</description> <description xml:lang=”da”>Montér en … Continue reading →
