I have a show-stopping problem while installing 10.10, and I hope you guys can help me – I've searched high and low for an answer, and I can't find one!
It's pretty straightforward: At some point during installation, the screen shuts down, just like it would if there wasn't any signal (if the screen is on but the PC is off, for instance). This means that I can't finish the installation. I've tried both the desktop and the alternate installer, and I've tried enabling all the “other options” when pressing F6 – also the expert-option available in the alternate installer.
No matter what, at some point, it seems to loose the signal, or go into sleep mode or something. I have an ATI Radeon 4890.
I've also tried editing the boot options by pressing F6 and instead of the ending looking like this:
cdrom/preseed/ubuntu.seed vga=788 initrd=/instal/initrd.gz quiet --
then, in a desperate attempt I followed this: http://tutorial.downloadatoz.com/how...ntu-10-10.html
so the parameters looked like this:
cdrom/preseed/ubuntu.seed vga=788 initrd=/instal/initrd.gz nomodeset single
Still the same. It seems to happen mostly when installing the base system, but has also happened while configuring timezone etc. I can't really figure out a pattern.
I also tried using “OEM mode” when pressing F4.
I would be very grateful for an answer!
