UDEV – Getting an Old Scanner to Behave..

Adventures With Linux ™ Posted on February 20, 2016 by RGFebruary 20, 2016

I recently acquired a vintage (2006?) Minolta Elite 5400 II scanner, and – according to the VueScan support info, I needed to ”set up libusb device protections”..   That info included a link to a somewhat ancient SANE USB support page – last changed in 2003!.. That rang a bell, and I guessed that I had to mess … Continue reading →

Fedora – Getting Rid of Unwanted ‘virtbr0’

Adventures With Linux ™ Posted on January 28, 2016 by RGJanuary 31, 2016

I did a clean install of Fedora 23 on my new ‘built from recycled components‘ crash-and-burn test system recently, and all went reasonably well – apart from – apparently – having to re-partition an already-partitioned drive (!)… After booting for the first time, I found that a ‘bridged’ network link – virtbr0 – was active..    As I … Continue reading →

Fedora – Installing a Working ZoneMinder..

Adventures With Linux ™ Posted on December 24, 2015 by RGDecember 24, 2015

Installed ZoneMinder ( https://zoneminder.com ) for some IP and WiFi cameras, and the first thing to remember is to not use the Fedora version!    This is due to the lack of ffmpeg and vlc support in that version, which makes the software somewhat less than useful.. Fortunately, there is good Fedora support, with a fully-functional version – … Continue reading →

KDE – Plasma Update May Lose ‘Favorites’, and a Fix..

Adventures With Linux ™ Posted on December 9, 2015 by RGDecember 9, 2015

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 →
