[probably OT] How to add a scancode?
by iadest 07 Aug '16

07 Aug '16

Hello This is probably not related to TDE, but Linux in general (Debian 8?). I have a multimedia PS/2 keyboard "BTC 9001A" (evtest reports it as "AT Translated Set 2 keyboard") and I try to use all its keys. Some are typical multimedia keys, while I program some other to launch applications in my TDE using "Keyboard actions" panel. Unfortunately not all keys are detected in OS by scancodes. Two keys generate only a EV_MSC event, while not giving scancode. Is it possible, by e.g. udev hwdb rule, to assign scancodes to these events? Here are results of evtest events test: Testing ... (interrupt to exit) Event: time 1470587826.798369, type 4 (EV_MSC), code 4 (MSC_SCAN), value 1c Event: time 1470587826.798369, type 1 (EV_KEY), code 28 (KEY_ENTER), value 0 Event: time 1470587826.798369, -------------- EV_SYN ------------ Event: time 1470587829.689519, type 4 (EV_MSC), code 4 (MSC_SCAN), value 1e Event: time 1470587829.689519, type 1 (EV_KEY), code 30 (KEY_A), value 1 Event: time 1470587829.689519, -------------- EV_SYN ------------ aEvent: time 1470587829.753248, type 4 (EV_MSC), code 4 (MSC_SCAN), value 1e Event: time 1470587829.753248, type 1 (EV_KEY), code 30 (KEY_A), value 0 Event: time 1470587829.753248, -------------- EV_SYN ------------ Event: time 1470587836.420023, type 4 (EV_MSC), code 4 (MSC_SCAN), value e5 Event: time 1470587836.420023, type 1 (EV_KEY), code 217 (KEY_SEARCH), value 1 Event: time 1470587836.420023, -------------- EV_SYN ------------ Event: time 1470587836.504746, type 4 (EV_MSC), code 4 (MSC_SCAN), value e5 Event: time 1470587836.504746, type 1 (EV_KEY), code 217 (KEY_SEARCH), value 0 Event: time 1470587836.504746, -------------- EV_SYN ------------ Event: time 1470587839.705553, type 4 (EV_MSC), code 4 (MSC_SCAN), value a6 Event: time 1470587839.705553, -------------- EV_SYN ------------ Event: time 1470587839.782562, type 4 (EV_MSC), code 4 (MSC_SCAN), value a6 Event: time 1470587839.782562, -------------- EV_SYN ------------ Event: time 1470587840.546297, type 4 (EV_MSC), code 4 (MSC_SCAN), value a5 Event: time 1470587840.546297, -------------- EV_SYN ------------ Event: time 1470587840.648616, type 4 (EV_MSC), code 4 (MSC_SCAN), value a5 Event: time 1470587840.648616, -------------- EV_SYN ------------ Event: time 1470587842.578400, type 4 (EV_MSC), code 4 (MSC_SCAN), value 1d Event: time 1470587842.578400, type 1 (EV_KEY), code 29 (KEY_LEFTCTRL), value 1 Event: time 1470587842.578400, -------------- EV_SYN ------------ Event: time 1470587842.761042, type 4 (EV_MSC), code 4 (MSC_SCAN), value 2e Event: time 1470587842.761042, type 1 (EV_KEY), code 46 (KEY_C), value 1 Event: time 1470587842.761042, -------------- EV_SYN ------------ The keys pressed are: Return key released, A, then "Search" custom key which works, then "Manual" and "Panel" keys (these two don't work - no scancode), then ctrl-C to stop evtest.

Update problems I don't master
by Thierry de Coulon 07 Aug '16

07 Aug '16

So I took a look at my packages and saw that there were updates to TDE (from 14.0.0 to 14.0.3, openSUSE here). I first choose "update if newer" for all my packages (in Yast) and ended in a disaster: apparently minimal X with a terminal, message about wrong permissions for Xorg. Setting these permissions right let me start X... but only in KDE 4! I thought the problem was with openSUSE, so I restored and tried updating only Trinity. This time the message is: .servauth.1668 does not exist cannot open /var/log/xorg.1.log please consult X.org foundation support There are plenty of lines with (EE) too Same correction to Xorg now brings up Icevm. I'm out of my depth here. I restored again and will make a copy install to investigate the matter. I understand this may be openSUSE linked but any suggestion can help. Not urgent however, 14.0.0 is running very well... Thierry

MX-15 sound loss in VLC
by Joe 06 Aug '16

06 Aug '16

I've had some sound problems in MX-15 with VLC and Trinity. The issue is solved... sort of. This is a link to the discussion: http://forum.mepiscommunity.org/viewtopic.php?f=100&t=40197 The short version is: After I installed KDE Plasma Desktop, the problems cleared up. Recently, they started again. If I log out of TDE, log into Plasma Desktop, log out of Plasma, then back into TDE, I have sound again in VLC.

New problem Ubuntu 16.04 TDE 14.04
by Jonesy 04 Aug '16

04 Aug '16

I'm trying to get moneydance to run on on 64-bit Ubuntu 16.04 -- the last application necessary to permit my wife to move off Windows forever... (Moneydance is a financial bookkeeping Java program somewhat ala Quicken.) I've installed the new "amd64" moneydance as instructed by their website, and I get this when I try to run it: |$ Moneydance |[kcrash] TDECrash: Application 'output.logl-gtk-tqt-application' crashing... .. and I'm dumped back at the command line prompt. About half the time I do NOT get the "TDECrash" message. I am simply dumped back at the command line prompt after 5-6 seconds. I just know if I tell the moneydance support I have a "TDECrash", they'll ask me to bring it up under Gnome.... _All_ I have is Trinity. How to debug this "TDECrash"? Jonesy

By Re: [trinity-users] LiveCD for Ubuntu 16.04 LTS
by Joseph Thames 03 Aug '16

I have a specific need for a tailored appliance version of what you are proposing. It is the bootable client appliance remote-desktop front-end for an end-user F95-based modeling language <http://www.metacalculus.com/lens/Spiritext.html> surrounded by xterm menu scaffolding <http://www.metacalculus.com/lens/MIDUS.html> in Perl. The remote desktop server is configured as a TDE R14 Ubuntu 14.04 Togglebox VPS now. It is part of the scaffolding for an end-user development (EUD) type of workflow called quality assurance and evolution (QAE) to extend a science exploration modeling technology called MetaCalculus <http://www.metacalculus.com>, which has been under continuous development for 50 years. End users can connect to this remote middleware via NX remote desktops <https://en.wikipedia.org/wiki/NX_technology> from the bootable appliances, similarly configured as TDE-Ubuntu or TDE-PCLinux <http://trinity.mypclinuxos.com/> distros on LiveCD or LIVE USB sticks. NX remote desktops communicate through FreeNX server apps, and NoMachine <https://en.wikipedia.org/wiki/NoMachine>, Remmina <https://en.wikipedia.org/wiki/Remmina> or X2GO <https://en.wikipedia.org/wiki/X2Go> client apps. The front-end PC and Togglebox TDE desktops are preconfigured mirrors that merge with each other, each having 20 virtual desktops accessed though side panel pagers (client-right opposing server-left). Taskbar panels similarly oppose each other (client-top opposing server-bottom). This is the front-end of a server-based MetaCalculus "automation lab" (AutoLab). This dual mirrored OS client-server "AutoLab ensemble desktop environment <http://www.metacalculus.com/doc/MIDUS/AutoLab_Desktops.html>" is designed for shared menu-guided workflow of an EUD-QAE team on a collection of virtual desktops, some on client and some on server via several connected interactive sessions spanning multiple servers, where up to 400 (20 x 20) sessions may be running simultaneously from a single PC workstation. And since NX supports desktop sharing, the desktop collection can span teams of overlapping user workflow sharing of teachers and students. As you can imagine, this dual OS Infrastructure as a Service (IaaS) ensemble is designed as an integrated front and middleware interactive workflow environment, which in turn fronts a background massively parallel Docker batch system for cloud supercomputing, using AWS et al <http://www.metacalculus.com/AutoKey/Linux_VAR_Wholesale_AutoLabs.png>. It can integrate "super SaaS" collaborative open-source development and K-12 end-user STEM education <http://www.metacalculus.com/AutoKey/Retail_Linux_USB_Appliances.png>. The modeling language, an F95 Extension "NeoFortran" supporting the modeling solver and kernel API of the original mainframe PROSE language <http://www.metacalculus.com/doc/imgzoom/HolonModelingInPROSE2.png>, can operate on all three of these computing layers (client PC, Togglebox VPS, or AWS et al) in various configurations (from client tablets for K-12 students to Togglebox VPS's for developers to AWS Docker jobs for high-fidelity big-data simulation models globally optimized in massive parallel jobs). Since the NeoFortran is an optimization modeling language <http://www.metacalculus.com/doc/FC/Synthetic_Calculus.pdf> which can optimize system-dynamics models <https://www.google.com/search?q=System+Dynamics+Images&espv=2&tbm=isch&tbo=…> translated via the XMILE protocol <http://www.metacalculus.com/AutoKey/MCSD/XMILE_Example.png>; and since optimization searching is embarrassingly parallel <http://www.metacalculus.com/doc/DigiCal/MOBHeraJupiter.html>, this integrated environment can support interactive SERIAL modeling of parallel optimization processing <https://docs.google.com/spreadsheets/d/1uLtZUZybn3uxYIxrmB5If8bNmWxM_ZASbfP…> in the cloud (similar to web searches), *without any parallel programming*. Simplification of this parallel processing is what I am working on now. Although I am a Trinity user, and have been since the fatal KDE4 fork that set back my downstream development by several years, I don't participate in this forum much, but I would like to see Trinity win the desktop race. As you can probably tell, most of the higher infrastructure I have shown in the links above was accomplished before that plasmoid fork. Ironically KDE (as one of the original two Linux desktop environments) is still more generally sanctioned than TDE. But the general trend (Windows style war) that forking trend was part of has hobbled the whole Linux community in another pursuit of the Tower of Babel. I would like to see the Trinity community adopt this LiveCD/USBstick Linux-boot ensemble as a QAE project and expand its desktop functionality. There are many TDE improvements I can think of that this QAE effort would mandate. Not the least would be integrated QA with the NX clients, which would significantly improve overall Linux interface reliability. This effort would enable TDE to trump the KDE style leadership with EUD-friendly practicality. The intent is to adapt more of an EUD "walled garden" approach, like Apple has achieved with the Mac, in order to broaden Linux EUD. In the above links you see evidence of a host of integrated EUD automation apps designed to lift the OS development focus out of the "Windows style swamp" that the Linux downstream community has blundered into. My intent is to emerge new EUD order out of this chaos by giving* the original computing language new life in the clouds: optimization of simulation modeling in parallel processing, without parallel programming*. This can be the killer app to transform the industry the way Fortran did originally, by exploding diversity in R&D; something IT middlemen cannot accomplish on their own, because they are not diversified enough to match the diversity of science, like end-users are. Thus we need to simplify and generalize advanced Linux EUD as this ensemble aims to do.

Upgrade of TDE DVD 14.04 to 16.04 -- FAIL
by Jonesy 01 Aug '16

I've just installed the Trinity LiveCD tde-ubuntu-14.04-desktop-r14.0.3-amd64.iso and performed all the updates. I commented out the entries in /etc/apt/sources.list.d/libreoffice-trinity.list -and- /etc/apt/sources.list.d/trinity.list and did a sudo do-release-upgrade to upgrade to xenial (16.04) and received the following: |Checking package manager |Reading package lists...
