This bug also affects me; latest karmic/9.10 as of 28dec2009. Problem encountered when replacing an older TFT monitor (Acer 24" - X243W) with a newer Samsung Syncmaster P2450.
Boot is fine UP TO loading Grub, at which it stalls with the same symptoms - blank, black screen, but backlight on (so it still receives a signal from the gfx card). No curser, no screen activity whatsoever. No system acitivity either, no HD activity. When i detatch the monitor (connected between gfx card (Radeon HD4650) and monitor with HDMI cable), boot continues fine, and I'm able to log in (albeit headlessly). I hear the usual ubuntu greeting sound after punching in the username and pw. I have a fast fix (thanks to Stefan Bader above for the hint!): 1) Boot your system in recovery mode (via grub). 2) Get your terminal and edit /etc/uspash.conf (if you want to use gedit: write 'sudo gedit /etc/usplash.conf' ) 3) it's a simple configuration file; edit the dimensions in the two lines to the native resolution of your display. 4) Save, do a 'sudo initramfs -u' - this will write the setting into the boot setup. 5) Reboot. My monitor still looks a bit mushy but at least it returned my sustem to a workable state. -- boot hangs with Dell 3007WFP-HC at Radeon X1950XTX https://bugs.launchpad.net/bugs/493834 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
