Dear all, this is the most weired desktop problem I had since using Linux for 10 years.
This happens after upgrade to 13.2 from 13.1. Look at this screenshot: https://dl.dropboxusercontent.com/u/3483854/font_blur_problem.png
For example, look at colum I, row 13, you can hardly read it.
The blurry font doesn't happen right after boot. It blurs a few minutes after boot. And it only affects newly drawn window - a window with clear fonts won't go blur unless it is redrawn.
It affects the GNOME desktop area (application bar on top of each app window, activities list), as well as applications (gedit, nautilus), as well as non-gtk, like jEdit libreoffice without gnome-integration.
It affects document area (Libreoffice Writer's content) as well as widgets, but it doesn't affect Chromium's document area.
It affects icons, but only gnome icons (not java application's icons), e.g. the current appplication icon on the lock screen.
Changing default gnome font with gnome-tweak-tool doesn't help. A change of font, in my case to "Droid Sans", instantly get all text in clear type, but in a few minutes the newly drawn windows, using the new fonts, gets blurry again. However, changing the font in Java application (jEdit, changing only document font to "Droid Sans Mono") has a lasting effect (on document area only).
It never affects web pages. See what's displayed in Chromium in the screenshot's background.
- If it is a certain font's problem, why changing font won't help? - If it is a gtk problem, why java apps are affected? - If it is a font system (freetype) problem, why gnome's icons are affected? - If it is a display driver problem, why Chromium web pages never have this? (although Chromium UI elements gets blurry like every other applications) - If it is a monitor problem, why the second external monitor also have this and why the screenshot also shows this problem?
The computer in question display card, according to lspci:
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
The graphical driver, according to /var/log/Xorg.0.log:
[ 71.043] (II) AIGLX: Loaded and initialized i965 [ 71.043] (II) GLX: Initialized DRI2 GL provider for screen 0 [ 71.055] (II) intel(0): switch to mode 1280x800@60.2 on pipe 0 using LVDS1, position (0, 0), rotation normal [ 71.101] (II) intel(0): switch to mode 1280x1024@60.0 on pipe 1 using VGA1, position (0, 0), rotation normal
Thanks for reading!
I used to have this problem on two prior occasions, on different computers. The first, I don't recall the video card, but the device could run in two resolutions, one was native, and the other was stretched. The stretched one would exhibit this. Back in Opensuse 12.3 release, I was using the community drivers for my AMD video card. They were no where near as good as they are now. In fact I think I posted on this list about this issue and was directed to a repository for Xorg produced by one of the guys working on it. That was a huge advantage for me, but it was no longer necessary by the time 13.2 rolled around as the beta Xorg has since moved into production. You might look into seeing if there is a later xorg for your release. In my case the bad spot would appear in different places, occasionally caused the mouse pointer to turn into a half-inch square, etc. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
