Does it? I don=B4t think so. The framebuffer subsystem should ignore all requests from within X, e.g.=20 fbset, setfont, etc run from xterm must not result in any screen distortions or=20 system hangs. A script running setfont, fbset, echo ? >=20 /sys/class/graphics/fb?/con_rotate, and cat of data to the framebuffer continuously on a framebuffer vt must not=20 harm X in the foreground. Setfont operations executed from a program running on e.g. vt1 must=20 change the context of that vt, not that of the current foreground vt. Some small fixes for xpan and ypan scrolling. Faster construction of the image data for unusual font dimensions. Did I miss something? Yes, at least a happy new year to all of you! cu, Knut ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
