My 8GB Raspbery Pi 4 finally arrived, and I was looking forward to trying Fedora 32 and KDE/Plasma on it, and comparing it to the Odroid N2 from a few months back.. ( http://rglinuxtech.com/?p=2689 ) The Fedora 32 aarch64 install is supposed to support the Pi 4 now, but the resulting sdcard image failed to boot, with … Continue reading →
This is one of those not-sure-if-bug-or-feature issues.. On my dual-boot Fedora/Win7 system, I needed to access a ‘shared’ NTFS (ntfs-3g) partition. When I came to add a softlink to the NTFS partition on the Plasma Desktop, the link existed, but nothing showed on the Desktop. Other softlinks – to EXT4 partitions – displayed OK. I tested with … Continue reading →
I created a combo runtime patch for NVIDIA 410.73 on Kernel 4.20-rc1, by combining the changes identified in my previous article ( see http://rglinuxtech.com/?p=2426 ) with the pm patch (see http://rglinuxtech.com/?p=2421 ). The result ran – eventually – after blanking/refreshing the display, with garbage characters at top/bottom, so all was obviously not OK.. ……………………… [ 121.826292] [drm] … Continue reading →
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 →
After some research, I decided to use an Intel-powered ex-Chromebook for my portable Linux project.. I settled on an Acer Chromebook c720p, as this could be ‘converted’ to run Linux natively, rather than in emulation via Crouton.. There are several articles on this, but I found useful info (and a chassis/mobo diagram) here: https://ankitrasto.wordpress.com/2015/02/06/clean-installing-linux-on-the-acer-c720pc720-chromebook-a-complete-guide/ If you are … 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 →
Just installed the kernel.org version of kernel 3.18-rc4 on the Odroid U3, and this time it completed the boot, but still had a ‘tombstone’: …………… cam-power-domain: Power-on latency exceeded, new value 413333 ns cam-power-domain: Power-on latency exceeded, new value 564291 ns Unable to handle kernel NULL pointer dereference at virtual address 00000010 pgd = ee328000 [00000010] *pgd=00000000 … Continue reading →
I had been experiencing occasional problems with X and KDE with the previous 3.11 kernel versions, and had reverted to 3.10.12, but have just updated to 3.11.2, and it seems to be better – so far…. VMware 10 compiles and runs OK, and NVIDIA 319.49 – with the 3.11 patch – works OK. I have seen reports … Continue reading →
Installed Kernel 3.10.1 on my main system, and everything seems to be working OK.. Changelog at: https://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.10.1 VMware 9.02 – with the 3.10 patches for vmnet and vmblock – compiles and runs, and NVIDIA 319.32 – with the 3.10 patch – compiles and runs OK, as well. With 3.10.0, I had problems with sound and the KDE … Continue reading →
I had tried running kernel 3.10, but encountered several problems.. The KDE desktop would ‘hang’, and the wifi connections (rt2800, using NetworkManager) refused to connect, most of the time, and kmix (sound mixer app) wouldn’t run.. 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 →
