I have Wheezy's X GUI pretty much set to my liking, using /boot/config.txt framebuffer settings for 1920 x 1200 on a 22" widescreen display. I have +450 and -450 left and right overscan settings. Things are centered nicely.
I increased the desktop font using the /etc/X11/xinit/xserverrc file with a DPI setting of 200, and have used the desktop settings and taskbar settings to increase desktop and taskbar font and icons. But I still have very tiny icons at the upper RH corner of any window I open (the ones that minimize, maximize, or close the window). I would like to increase those so I can see them (they look like periods right now). How can I increase the size of those icons?
