Public bug reported:
Binary package hint: xserver-xorg-video-intel
Today I upgraded my RAM from 1GB to 4GB. Everything worked fine but I
noticed that scrolling in Firefox and dragging windows is noticeably
slower than before. I checked this again by removing 2GB and got the
same results (i.e. 2GB -> fast scrolling, 4GB -> slower scrolling)
I suspect it has to do with this line from the X server:
(WW) intel(0): Failed to set up write-combining range (0xd0000000,0x10000000)
If this is something the kernel is responsible for, please feel free to
reassign accordingly.
I have no options in my BIOS to change anything that might be relevant
to this (memory mapping, etc.)
This is a Samsung Q45 with Intel X3100 graphics.
I'll attach more debug info.
