** Summary changed: - Ubuntu graphical boot uses too high horizontal frequency (LCD display problem) + Radeon 9200 SE "not synchronised signal" with usplash and consoles

When + booting with usplash or when trying to access any console, I get "not + synchronised signal" I think that Ubuntu should detect that LCD monitor is installed during install and configure kernel for LCD display. Or to use lower monitor frequency during Linux boot by default. It is possible to fix the problem by adding a parameter for kernel (vga=791), like this line in /boot/grub/menu.lst: # defoptions=quiet splash vga=791 It has to be done manually and "update-grub" updates kernel lines in menu.lst; Ubuntu cannot do this during install, it is a bug from my point of view. -- Radeon 9200 SE "not synchronised signal" with usplash and consoles https://bugs.launchpad.net/bugs/81206 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
