Strange font problem; missing pixels, lines, choppy.

fc-cache

Is that a command or a folder name?

[Cornova]

fc-cache -r --really-force command (erase all existing caches, then rescan) Didn't work

I had this problem with the fonts and it was cause by having excluded range check marked. Go into fonts and click on configure and uncheck mark exclude range. If you have the same problem I had.

It was already unchecked on mine.


Someone suggested I try what was suggested in this thread. However, I am unable to move the files into the /etc/profile.d/ by pasting or dragging (Access Denied). Do I need to enable permissions? If so, how?

you need to have root acsess for that.

you can open a root dolphin by typing "kdesudo dolphin" in Krunner (alt+F2) and hit enter,,, enter your password when prompted and then be careful, you can do anything now, and wreck your system

Thank you, I was able to finish the instructions in the thread after using your command. Unfortunately although the font appearance changed, the problem persists. I will have to use another distro if I can't solve this which stinks because the interface is starting to grow on me and I want the full disk encrypt feature.

The only info I can add is that the lines and missing pixels are random, that is I could open the browser and see a complete mess on the wikipedia homepage, close it, open it again and be perfectly clear, or maybe just a few lines etc.

I notice that in an earlier post you said the problem didn't occur in a native KDE program such as Rekonq, but it is occurring in GTK based programs such as Firefox.

This led me to wonder if you have both gtk2-engines-oxygen and gtk3-engines-oxygen installed?

[Cornova]

I have seen similar problems and it had nothing to do with the fonts but it was a video settings issue.
As the Intel video driver is just about native it's hard to tweak it but why not try to lower the scan frequency from the default 75Hz to something like 60 Hz.
xrandr should offer some easy ways of playing with the settings, you could even try to change the resolution and see if it helps.

My only options are "auto" and "60hz" and it was set to 60hz. I tried lowering the resolution but no change.

If you mean system settings > appearance > GTK+ appearance > widgets, I see oxygen-gtk set with Raleigh as another option.



Someone on the Ubuntu forums, actually the person from the font thread I linked, suggested that it may be a Vsync problem that is supposed to be addressed with the next KDE version. However I don't know for sure if that is what the problem is.

No, I mean the software packages "gtk2-engines-oxygen" and "gtk3-engines-oxygen". You can check whether or not you have them installed by using Muon Package Manager's search function. You probably already have gtk2-engines-oxygen installed, but it's possible that gtk3-engines-oxygen isn't.

The setting you mentioned (system settings > appearance > GTK+ appearance > widgets) uses those packages to control the appearance of GTK programs in KDE. The first package is required for programs that use GTK2, the second is for GTK3 programs.

Under Muon, neither gtk2 or gtk3 shows up under search or is listed as installed.

Edit: googled the "sudo apt get" for installing both and they are both already installed. Thanks for the suggestion though.

Make sure you are using Muon Package Manager, and not Muon Software Center. Here, both "gtk2-engines-oxygen" and "gtk3-engines-oxygen" are installed.

Ah, I see like the synaptic manager or whatever.. Well I just tried installing both from the terminal and they were already on, so I can eliminate the possiblity.

[Cornova]

I just ran the Linux Mint Cinnamon DVD with the intention of installing it, but as it turns out, that too has this font issue, which means it is not KDE causing the problem. Note however that I did not have this issue with Gnome on Ubuntu 10.04. Anyone have any idea why it would all the sudden be an issue?

Solved

The solution to this issue is to create a file named xorg.conf, paste the following into it and save to desktop or wherever:

Section "Device"
 Identifier "Intel"
 Driver "intel"
 Option "DebugWait" "True"
EndSection

Once saved, move xorg.config to /etc/X11

If you don't have permission to move it, open the terminal and paste the following:

sudo chmod 777 /etc/X11

Enter password, close the terminal, shutdown/restart the computer.

Someone posted this solution on another thread that was linked here.
