Devuan ASCII & TDE ... call for devs :-)
by Dr. Nikolaus Klepp 01 Jan '18

01 Jan '18

Hi all - especially Slavec and Tim :-) I don't know if somebody is on the devuan mailinglist, so I'll place this link here: https://lists.dyne.org/lurker/message/20171214.132959.b8c0d989.en.html Could TDE provide official packages or a an official repository for devuan ascii, as KatolaZ ( KatolaZ <katolaz(a)freaknet.org> ) is asking for (see posting below)? As fas as I can tell, Slavecs repository has been stable for ages now, and it works perfectly with ascii. So ... take the chance? Nik Am Donnerstag, 14.

In comparing our respective compiler options used to build tdelibs, I notice that I had compiled with "-fvisibility=hidden -fvisibility-inlines-hidden". I think this *might* have something to do with your error. Since I had not actually added these options to CXXFLAGS, I believe that they are inserted by cmake when you pass it "-DWITH_GCC_VISIBILITY=ON". Vince

Hi, I want to build trinity core and did follow the order at the website. As it was mentioned as optional I didn't build avahi-tqt and tqca. I have disabled cups too.

If that is correct, I did not see any issues with it despite the fact that the GDK_SCALE environment variable is not set. I am curious about one thing you mentioned: are actually using TDE (the desktop environment per se) with a window manager other than twin? If so, I would be interested to know how that worked out for you as I had noted that alternative window managers can be configured. That might solve at least the "microscopic window resizing arrows" part of the problem. Thanks, Vince -------------------------------------------------------

I tried the High Contrast style and while I agree that its appearance leaves a lot to be desired, it did seem to remedy matters by presenting larger more visible window/menu controls. That says to me that modifying an existing style might provide a solution to the problem at hand. Perhaps that won't be as modern a solution as a true "it just works" dynamic scaling of these graphical controls, but it will be good enough for me if it allows me to run TDE on laptops such as these at native resolution. Interestingly, one of the things that was not corrected by that style was the really tiny window resizing cursor. I investigated further and noticed that my favorite cursor theme "Xfree theme redglass" now has an annotation "incomplete for TDE" -- I had never noticed that before. I guess the theme is incomplete because it lacks the "redglass" window resizing cursor. Without it, this particular cursor becomes "Adwaita", a theme that apparently doesn't scale at all. I guess I will also have to learn how to "complete" the redglass theme. -------------------------------------------------------

TDE on dense small screens
by Vincent Reher 12 Dec '17

12 Dec '17

Hello TDE Developers, I recently purchased a Dell XPS15 laptop for my daughter and before I turn it over to her, I am experimenting to see what must be done to make it usable under Linux/TDE for those with no better than normal eyesight. Per EDID, the laptop's native screen resolution is 3840 x 2160 and its physical screen dimensions are 346 x 194mm (~15.6" diagonal). My objective is to run the laptop at native resolution both inside and outside of X (no re-scaling). Using the EDID metrics, it is pretty easy to determine during boot an optimum terminal font (ter-i32b.psf) and X font scaling (Xft.dpi=240). After that, using the TDE control panel to increase panel and icon sizes produces a nice looking desktop environment … almost. The remaining issue concerns TDE window/menu controls that are too small. These include window resizing double-arrows, window scrollbar and associated up and down arrows, the menu-submenu right arrow, list expand-collapse (+/-) controls, checkboxes, and radio buttons. I suspect that these resources are part of QT3 but don't really know for sure. I suspect QT3 because applications that do not use that toolkit (e.g. LibreOffice and Firefox) do not manifest the problem. I am hoping that somebody more knowledgeable about GUI configuration and programming can point me in the right direction. Is this something that can be corrected via a configuration file (e.g. qtrc)? If not, can somebody point me to where in in the source code tree I should be looking and what I would need to do to correct this? Of course, if HiDPI issues have already been addressed by others in the post R14.0.4 source code, that would be great. Thanks in advance for your insights and help. Vince Reher

TDE for Debian & Devuan

Being a bit busy at the mo (and maybe a little lazy) can anybody tell me if there are significant differences between TDE for Debian & Devuan? If I were using Debian Stretch _without_ systemd, which would be the better choice of TDE install? Cheers, Mike. -- Mike Howard

To be clear, I have no issue whatsoever with the fonts -- they look great on this display with Xft.dpi=240, perhaps in part due to my past efforts at making fonts look reasonable on Linux desktops. And the desktop/panel icons are fine after stepping up to larger sizes (no scaling). It's just those apparently fixed-size bitmap images used for window/menu controls that are way too tiny. If indeed the problem lies in QT3 and it cannot be "configured away" either during build time or run time, then I simply ask for somebody more knowledgeable to point me in the right direction so I can start looking and experimenting with the source code. I am also not suggesting TDE be ported to QT>3. I know that is a non-trivial effort and would not be feasible. Also, I am not even sure that QT fixed this problem until the 5.x versions (http://doc.qt.io/qt-5/highdpi.html). To downsize from native resolution on this laptop would be to admit defeat and loose a touted feature. It's not going to be a problem for my daughter since most of the software she needs to run is "windows only" and the laptop's pre-installed Windows 10 does not seem to have any problem at all. It may be a problem eventually for me should I choose to get a similar laptop and stick with TDE.
