I can, for some reason, not get it to show anything but the output from the booting kernel and then the login-prompt and this slightly makes my reason for attaching a console to my machine go away as I might need to change boot parameters in case my remote machine misbehaves (my remote machine is ~100km away, so I can't just go there and sort things there).<br><br><br>I found numerous other posts like this one, but from people on other distributions, who actively mentions that they get the grub-menu on their console.. so. Your experience, please :)<br><br>PS: I'm using Debian Testing (Squeeze)renéhttp://daily.denada.dknoreply@blogger.comtag:blogger.com,1999:blog-630168170911892729.post-32972074055254836622009-12-11T12:40:49.000+01:002009-12-11T12:40:49.000+01:00In my Ubuntu 9.10 server installed on an industria...In my Ubuntu 9.10 server installed on an industrial PC (PentiumIII) your suggestion works fine 100%.

So that's the reason why I'm using 9600 - it's for compatibility :-)<br><br>Good luck...Petr Ruzickahttp://www.xvx.cznoreply@blogger.comtag:blogger.com,1999:blog-630168170911892729.post-80514709594606638852012-03-11T00:56:25.000+01:002012-03-11T00:56:25.000+01:00You should use GRUB_CMDLINE_LINUX instead of GRUB_...You should use GRUB_CMDLINE_LINUX instead of GRUB_CMDLINE_LINUX_DEFAULT otherwise you'll miss the console when you boot in rescue ( single user ) mode via a grub entry.Emmanuel Kaspernoreply@blogger.com
