Upon further reflection, although possibly we have been overzealous with using OnlyShowIn=TDE, I suspect not. We do need to use that directive for certain apps, but I don't think that is the root cause of the problem described by the blog author. I suspect the problem with other environments not seeing Trinity apps is environment variables. As just about all of us build Trinity to install to /opt/trinity, not a single environment default configuration will find Trinity apps with standard environment variables. Specifically the XDG_* variables that affect finding trinity files. I believe then the first hurdle is how to help other environments find all Trinity *.desktop files. I wonder whether we should install the menu files to /etc/xdg/menus rather than /etc/trinity/xdg/menus. A caveat: when KDE4 is concurrently installed with Trinity, the respective environment menu can become a hopeless cluttered mess. This is true in my xfce test. We have a build-time option to add "[KDE4]" to all KDE menu items, but that might affect only the Trinity menus. I'd have to run a build test to see any effects on the Xfce menu. This topic deserves further investigation. Darrell

OnlyShowIn=TDE or NotShowIn=KDE?
by Darrell Anderson 11 Feb '14

11 Feb '14

Recently Trinity was given a nominal public review in a blog: http://anarchic-order.blogspot.com/2014/02/installing-trinity- desktop-environment.html The author offered a caveat: "The Trinity-DE applications are only available through the Trinity- DE desktop. While all the other applications installed on your system show up in the TDE menus, because of the way Trinity-DE loads its menus, if you log in with Xfce, the Trinity-DE applications will not be seen." Most Trinity *.desktop files use OnlyShowIn=TDE, which causes the author's observations. Should users of other environments (many window managers support a menu system too) be prevented from using Trinity apps? Probably not. The original motivation for using OnlyShowIn=TDE is conflicts and confusion in the Trinity and KDE menus because many apps share the same name. Perhaps NotShowIn=KDE is more apprpriate than OnlyShowIn=TDE? I believe we should resolve this before releasing R14. Comments? Darrell

khelpcenter - howto identify icons opened? (brokenpng.c)
by David C. Rankin 11 Feb '14

11 Feb '14

All, There are a number of png files in TDE that generate errors on opening due to outdated png header information. I would like to identify which icons these are. For example when opening khelpcenter I receive the following messages: 03:03 valhalla:~> khelpcenter help:/khelpcenter/releasenotes khelpcenter: WARNING: Main template file name is empty. libpng warning: iCCP: known incorrect sRGB profile libpng error: IDAT: invalid distance too far back libpng error: IDAT: invalid distance too far back libpng error: IDAT: invalid distance too far back libpng warning: Interlace handling should be turned on when using png_read_image libpng error: IDAT: invalid distance too far back libpng error: IDAT: invalid distance too far back libpng error: IDAT: invalid distance too far back libpng warning: Interlace handling should be turned on when using png_read_image Apparently, the problem is out-of-date png header information. Searching I stumbled across a minimal bit of source that is supposed to fix the issue, but only if compiled on older versions of libpng. Looking at the code, the crux of it is to rewrite the first 8 bytes of the png header. I've attached it for experimentation. It builds well on all of the boxes I have, but I suspect you have to force it to build against libpng 1.2 in order for it to do what it is supposed to. I'll continue to experiment. If you have few spare minutes give it a try and let me know if you can see any discernible difference in the new/old png files. I haven't yet. -- David C. Rankin, J.D.,P.E.

cmake conversion audit
by Darrell Anderson 11 Feb '14

11 Feb '14

I have always been suspect of all the cmake conversions as being incomplete. Some obvious examples include tdemultimedia and tdewebdev. Conversions were started but never completed. Other examples include amarok (bug reports 818, 1917). Last night I noticed a directory in tdepim that does not compile because no CMakeLists.txt file was created during the cmake conversion. There are other cmake issues, such as no cmake macro was written for converting man page docbook files to man pages. The automake packages still compile fine but the cmake converted packages no longer build the man pages. (Bug report 1830.) I don't know how we should audit the cmake conversion process. Possibly one way is search the source tree in the known conversions for Makefile.am and look for a coexisting CMakeLists.txt. That does not mean the conversion is complete but would expose certain incomplete conversions as I discovered last night in tdepim. We need a way to audit cmake conversions. Any ideas? Darrell

Yeah, Linux is ready for the desktop.... You have tested sound with the aplay and play commands, which validates your hardware and alsa. Start an alternate desktop to at least isolate the problem to only Trinity. I don't know about the above messages, but seems arts is not starting or is not loading completely. Another idea is permissions. I quite often log into my desktop as root to test permissions issues. Not tdesu, actually logging in as root. I don't prescribe to any aspect of the anti-root religion and logging in as root is a quick way to determine whether a problem is permissions related. Also try with a fresh profile. I have a couple of testing accounts I use to try various things without touching my normal accounts. With the testing accounts often I 'mv ~/.trinity ~/.trinity.bak' and then start Trinity. That creates a new ~/.trinity profile directory. When I finish testing I 'rm ~/.trinity' and then 'mv ~/.trinity.bak ~/.trinity'. With a fresh profile directory you should hear the stupid login sound file if arts is loading correctly. This at least narrows the issue to your profile or Trinity in general. When I have arts issues I delete the tdesycoca cache files, ~/.mcop, and all the Trinity socket and temporary files. This is a big reason I don't use graphical logins. I can exit X and be back to the command line without worrying that the login manager and X are still running. Provides an easy way to debug and delete files. I also just now remembered there is an arts config file. Once upon a time in the KDE3 days that file caused problems with one of the options, but I no longer remember the details. Anyway, try renaming ~/.trinity/share/config/kcmartsrc. And yeah, the tdemultimedia conversion to cmake never was completed. Darrell

Latest Build broke ALSA sound (play works - aplay screaches)
by David C. Rankin 10 Feb '14

10 Feb '14

All, I just installed all of the packages from the 2/8 - 2/10 build. The initial display of khelpcenter worked fine, but I noticed that I had no sound. After fighting with sound in the first set of packages, I was surprised that sound would just quit working in the latest set. I then opened konsole and tried: 21:52 valhalla:~> aplay /opt/trinity/share/sounds/KDE_Startup_1.ogg Playing raw data '/opt/trinity/share/sounds/KDE_Startup_1.ogg' : Unsigned 8 bit, Rate 8000 Hz, Mono I got a horrible screaching sound from speakers. I then tried: 21:52 valhalla:~> play /opt/trinity/share/sounds/KDE_Startup_1.ogg /opt/trinity/share/sounds/KDE_Startup_1.ogg: File Size: 124k Bit Rate: 125k Encoding: Vorbis Channels: 2 @ 16-bit Samplerate: 44100Hz Replaygain: off Duration: 00:00:07.95 In:100% 00:00:07.95 [00:00:00.00] Out:382k [ | ] Hd:0.1 Clip:4 play WARN rate: rate clipped 2 samples; decrease volume? play WARN dither: dither clipped 2 samples; decrease volume? Done. It sounded great. So checking, play is provided by sox 14.4.1-4. That begs the question, Why does play work fine but aplay fail? Suggestions? -- David C. Rankin, J.D.,P.E.

Patch to add trash can configuration dialog to set storage limits
by Darrell Anderson 10 Feb '14

10 Feb '14

I found a 3.5.9 patch to add a trash can dialog to set trash storage limitations. The dialog would look like this: http://tokoe-kde.blogspot.com/2008/08/size-limits-for-trash.html The patch did get submitted in the KDE bugzilla but never got merged into 3.5.x. I converted the patch to TQt3 and added an option to populate the konqueror configuration dialog with a trash icon that should show the same dialog. The patch fails to build for me: /dev/shm/tdebase/tdeioslave/trash/ktrashpropsdlgplugin.cpp:226: undefined reference to `TrashImpl::trashDirectories() const' /dev/shm/tdebase/tdeioslave/trash/ktrashpropsdlgplugin.cpp:141: undefined reference to `TrashImpl::trashDirectories() const' /dev/shm/tdebase/tdeioslave/trash/ktrashpropsdlgplugin.cpp:61: undefined reference to `TrashImpl::TrashImpl()' /dev/shm/tdebase/tdeioslave/trash/ktrashpropsdlgplugin.cpp:62: undefined reference to `TrashImpl::init()' If you are interested then I have attached the patch to bug report 1923.

Drop previous patches and try only this attached. I rebuilt tqt3 and tdebase and my build logs and error log are again quiet. Thank you. Is this something I have to run all the time or will this be pushed to git? Darrell
