By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Description Michele Calgaro 2018-03-09 09:28:30 CST 
TDE Control center only offer the choice of 96 or 120 DPI for the fonts.
With modern screens this may not be enough. 
A slider in the range 64-256 would offer more flexibility with the variety of displays.
Comment 1 Felix Miata 2018-06-28 21:31:03 CDT 
Most anyone who would try anything below 96 is almost certain to be unhappy with fonts. Modern fonts are not designed for any less nominal display density. There might be some infinitesimal few happy with the old xfs 75 dpi fonts, yet some apps, web browsers in particular, will override DE DPI with a 96 minimum. On the other end, there are already laptop displays marketed with more than 330 DPI.

Based on the awful usability I saw quite a long time ago of the Gnome or XFCE DPI scaler, and my vague recollection of the DPI slider in post-XP Windows, I'd much rather see a select list than a slider, with increments of 12 if a moderate list is acceptable, 24 (which both 96 and 120 are) if less. Font behavior (steps between adjacent size increments/decrements) can be rather disconcerting with odd DPI selections (not a multiple of 12).
Comment 2 Michele Calgaro 2018-08-19 07:53:43 CDT 
This requires the following:
- changes in Login manager, this is system wide and are used by tdm at the beginnning. New code is required for this.
- changes in kcontrol font section, to allow overriding the system wide settings on a per-user basis. This is an extension of the code already existing.

Support for range 64-512 in user session has been added in commit e8d866450 (R14.1) and a1a836e14 (R14.0).

Support for TDM login screen is still pending.
