Hi Alan, It appears, Fedora 21 is using python3-pillow 2.6.2 according to RPM find. Pillow 2.6.x has been problematic on several distros I've used / tested. The problems seems to be isolated to those using Pillow v2.6.x ( Debian Jessie, Ubuntu 15.04, etc. ). Distro's using earlier or latter versions of Pillow do not exhibit the same problem.
To resolve this on Debian / Ubuntu, I installed the Pillow build dependencies then installed ( compiled ) the latest version of Pillow via Pip3. FWIW, Here's what I used for Jessie / Utopic: * Open a termainl, Ctrl+Alt+T * sudo apt-get update * sudo apt-get install libfreetype6-dev libjpeg-dev liblcms2-dev libtiff5-dev libwebp-dev libwebpmux1 mime-support tcl8.6-dev tk8.6-dev zlib1g-dev * sudo pip3 install --upgrade pillow I'm not entirely sure if the real root cause is Pillow or the combination of Pillow 2.6.x being built against tcl/tk 8.5 or not. But building form Source ( using pip3 ) against tcl/tk-8.6 seems to resolve the horizontal display crashes on Jessie and Utopic. 73's Greg, KI7MT On 6/29/2015 6:14 AM, Alan VK2ZIW wrote: > Hi Joe and Bill, > > I compiled WSJT SVN r5635 on my Ubuntu 14.04 LTS x86_64 box and > yes, the "fast" modes JTMS etc do not crash and do not gobble memory. > > So, I guess, Fedora 21 uses later Python etc. libraries. > > Earlier this year, when Fedora 21 first came out for ARMv7 (Pi and clones) > I did compile up WSJT, but obviously did not adequately test it. > I tested it today and the "fast" modes crash in the same way as > the Intel architecture. > > As I see it, "Fedora" is THE "Red Hat" linux flavour. > > They (Fedora) put a LOT of work into the ARM platform. > This allows ultra low power apps for balloons etc.. > > And, of course, remote sites on solar power. > > As far as I know, you access to my ARM box here has not changed. > You have GUI via RDP.
