comment dual monitor with uvesafb / Intel 945GME?
AFAIK the basic /dev/fb interface (the universal ioctl calls common to all drivers) itself doesn't offer any multi-screen support, hence uvesafb doesn't either. Perhaps more specific drivers come with proprietary extensions - I don't know. KMS is completely new to me, but looks promising. Will try to learn more about it... ;-)

comment dual monitor with uvesafb / Intel 945GME?
This is not for a tty. I'm writing directly to the framebuffer memory. In theory, I could draw the second screen "below" the other (starting after the last pixel offset of the first screen) and set ypan for the second screen only. But apparently you're right, I can't find a way setting ypan for a single screen only - the generic framebuffer interface (not just uvesafb) doesn't seem to have the concept of a "screen" (despite some structs being named "*SCREEN_INFO").

comment dual monitor with uvesafb / Intel 945GME?
Well, uvesafb at least has support for Y-panning (ypan) and the generic framebuffer structs seem to know about "screens", so maybe I can set the second screen to a different Y pan position (exactly at the end of the first screen), so that can draw to both screens independently. I'll try to write a test program for that to verify.

comment How to estimate loops/time for completion of GNU ddrescue (1.18.1) using current status?
The cable disconnect will usually cause logical errors (ie. the data on the disk is not 100% valid), but won't cause physical problems with the drive - unless you dropped it at the same time. ddrescue can only try to recover physical problems and won't help with logical errors at all. For the latter, try fsck or alike..

comment Can I make low-level changes on a root fs mounted RO?
Ok, the thing that confused me was that fsck for the root fs is started by a standard init.d script (checkroot.sh), i.e. while / is already mounted ro. I modified initramfs so that fsck is done before even mounting root and in case of a critical error it can reformat root and restore a safe backup from another partition.

comment Where is fsck startet for the root filesystem at boot?
The problem is that the rootfs needs to be changed from time to time (application upgrades, configurations) and I can't update the initramfs each time. Instead, falling back to a older backup and re-applying the changes is the better way for me.
