But if it worked previously it should work now ;-) Are there any problems on the framebuffer console? You wrote that the fb=20 console comes up fine, but please confirm that scrolling is ok. Are there any problems left after you reach the state of your third=20 picture? Switching between the fb console and X works flawlessly then? Are there any problems if you use the standard resolutions, eg 1024x768=20 or 1280x1024? Try a fbset -vxres 2048 -vyres 4096 after your first fbset. Does that=20 change anything? Please send dmesg logs of kernel 2.6.15.6 and 2.6.16 after adding=20 verbosity=3D2 to the modprobe of cyblafb - everything from the point of loading=20 cyblafb to your third picture. Also include the X server logs. Maybe it=B4s a good idea to send= =20 those logs to my private address Knut_Petersen@t-online.de. cu, Knut ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting langua= ge that extends applications into web and mobile media.
