[jira] [Commented] (NETBEANS-2360) HiDPI scaling (and anti-aliasing on KDE) not applied automatically on Linux

    [ https://issues.apache.org/jira/browse/NETBEANS-2360?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17516604#comment-17516604 ]

---------------------------------------

Hi, Javier!

As you may have noticed, Java only supports either 1x or 2x HiDPI scaling on Linux. So the script I provided only applies the 2x scaling when the desktop's scaling is exactly 2x (192 dots per inch). In your case it seems you have configured a 162/96=1.6875x scaling factor? Could this be right?

Could you try setting your desktop's HiDPI scaling to exactly 200%, and then see if the script picks up on that?

(I suppose I could change the script to scale NetBeans to 2x if the desktop's scaling level is more than 1.5x, or perhaps some higher threshold. But I figured it was better to let the user increase their font size instead in these cases.)

> Running NetBeans 11 on Kubuntu 18.03, GUI text size does not seem to take into account the system's default HiDPI scaling. This was reported in a Twitter thread on https://twitter.com/nicktail/status/1114789604337405952 . Note that Window decorations seem to be the correct size.
> Setting the GDK_SCALE environment variable seems to fix the problem, if I understand the originally reporter correctly. This could probably be done easily from the NetBeans launcher script (netbeans/bin). But it wouldn't fix the problem in multi-monitor setups. We should investigate what could be done to make scaling work properly in multi-monitor setups involving one HiDPI screen and one non-HiDPI screen.
> Before merging a patch to the launcher script, it should be tested on a couple of different Linux environments, using both HiDPI and non-HiDPI screens. Note that the UNIX launcher script is also used on MacOS.
