Hi folks!!! For July 19 and 20th I will be attending the Desktop Summit as well as the kernel summit. The kernel summit is unfortunely by invitation only :-( but the desktop one is open to the public. To the people that have worked hard on this project let me know if you want to go to the desktop summit. If you don't have the money I will work something out for you. I plan to give a demo of Ruby there!!!! So in the next few weeks I'm going to set up a box to send to the conference. My goals for the demo are to have a 4 desktop system. I like to get KDE running on one desktop and Gnome on another. Then the other 2 heads would be a Embedded JVM running and a regular console. |

I suppose you put your presentation somewhere after Desktop summit. Will you post the link to this list, too? BTW I will try to do the same under x86_64 FC2 soon.

Current CVS contain ugly VGA driver (?) bug - tty1 cursor lost positon after vt switch. I have no idea where that bug lives. You must patch or hide with fbdev. gpm - Your tree breaks (/dev/vc/0) . /dev/vcs* - I don't know how to use it, rather that is broken. > My goals for the demo are to have a 4 desktop system. 4 desktop system, seems, well tested is Nvidia adapters only, with closed source drivers. I agree usage of easy sytems, where each user have soundcard too. Sound setup is hard, because each program use own sound driver. > I like to get KDE > running on one desktop and Gnome on another. gdm allow choose session.

This feature does not distrub starting number of xf86 and i never try locate it. Of course ruby needs for good "marketing manager" , which tell anybody about benefits of ruby. Aivils |

I tested it. It doesn't compile as-is. That seemed to be a
trivial missing pair of curly braces, so I added them.
(See below)
Then it compiled, with the following warnings:
drivers/video/fbmem.c: In function `fb_resize_vt':
drivers/video/fbmem.c:1014: warning: implicit declaration of function
`acquire_console_sem'
drivers/video/fbmem.c:1016: warning: implicit declaration of function
`release_console_sem'
Probably a missing header - it linked and gave me a kernel. It hung, though.
Could this be the problem, or is it a more difficult deadlock issue with
the semaphore?
The kernel hung after initializing the framebuffers, before
setting up fbcon. So all I got was a screenful of pre-fbcon garbage.
It is interesting to note that the first keyboard was dead, it did
not react to "numlock" or sysrq sequences. The second keyboard
was fine, it reacted to numloc/capslock by turning the LEDs on/off
as usual, and I could sync & reboot using sysrq sequences there.
My guess is that this looks like some sort of deadlock. Perhaps the
console semaphore isn't free, or something else needs it?
Do the "printk" that tells us about "160x64 color fbcon takeover"
need the semaphore?
Only one console locked up.

Added a } here. Without these braces I got
a syntax error on the "else" on the next line.
