Re: Hi Def for Lithium

^ I think the problem is that barebones Xorg systems don't automagically recognize the correct DPI at all.
No idea where the default value of 96 comes from, but I made the effort to measure & calculate what it really is for my monitor - it's 99. And when applied, it makes a big difference wrt e.g. font rendering.

The 96 DPI comes from the Xorg devs deciding to make Linux bug compatible with Windows and even though MS fixed the bug in Windows with the release of Windows 7 Xorg says NOTABUG and WONTFIX.

Their attitude is the fix is Wayland.

One of the many bug reports:

https://bugs.freedesktop.org/show_bug.cgi?id=23705

Previous to this xserver would automatically set the display DPI correctly.

Re: Hi Def for Lithium

@jeffryC thanks for the link.
@ohnonot a change from 96 to 99 seems rather small to make a "big difference" to font rendering?
And:

While you can set any dpi you like and applications using Qt and GTK will scale accordingly, it's recommended to set it to 96, 120 (25% higher), 144 (50% higher), 168 (75% higher), 192 (100% higher) etc., to reduce scaling artifacts to GUI that use bitmaps. Reducing it below 96 dpi may not reduce size of graphical elements of GUI as typically the lowest dpi the icons are made for is 96.

My own display's real dpi is 90, and I've tried adding this to my autostart file:

xrandr --fbmm "$(xrandr | sed -n '/ connected / {s/.* \([0-9]\+\)mm x \([0-9]\+\)mm/\1x\2/p;q}')"

But the results - if any - won't be seen till I've finished reading the other forum posts and logged out.

EDIT: results were undetectable to my eyes.

Re: Hi Def for Lithium

Back to my initial problem, this is not an issue of font rendering, nor tint2 issues. Nor do I think there's a scaling issue. Maybe my NVidia GForce 210 drivers need updating - they didn't need tweaking in Hydro or Helium, and I doubt NVidia has made any updates to these in the past two years.

My 30" Apple Cinema display works great with every other distro I've tried, incld'g plain old debian buster w/ an XFCE DM. Yet my 24" Apple works great with Hydro, Helium & Lithium.

So as a work around, can someone help me? I'd like to download the 64bit AMD Helium ISO so I can drop back for the time being. I can't seem to find it anywhere. Thx in advance.

Absolutely love BL, but am quite frustrated with Lithium at the moment.

an update: I found an ISO torrent for helium 64bit. Anybody out there not recommending upgrading helium to buster (per this topic: https://forums.bunsenlabs.org/viewtopic.php?id=5007)? thx again for your patience with a non-bit-twiddler.

Re: Hi Def for Lithium

Back to my initial problem

I don't mean to be facetious, but what was that?

my NVidia GForce 210 drivers

Have we established yet what drivers are in use on the problematic (?) system?
