Adding radeon.new_pll=0 to the kernel command line solved the issue for
me.
So I added this (radeon.new_pll=0) for the GRUB bootloader. It's in the
/etc/default/grub file in the GRUB_CMDLINE_LINUX_DEFAULT parameter (now
it is: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.new_pll=0").
Laptop: ASUS Z53J series, MODEL=Z53J, MB ver.=F3JP, embedded VGA card=Radeon Mobility X1700.
Ubuntu flavour: KUbuntu.
No problem with Karmic Koala, the problem appeared after an upgrade to Lucid Lynx. Moreover, it appears after a fresh install of Lucid Lynx or while usind the Live-CD.
Problem: the screen flickers after the boot splash screen or just after login in and moving the mouse (apparently). The screen is unreadable.
Result of lspci -v (for the VGA part) :

Should I file a new bug report for more details ?
