Bug Description
On the Ubuntu-
An alternate key sequence was noted: Alt-SysReq-K.
I've been asked to post a bug detailing that this key sequence does not seem to have any effect, and on some of my systems simply brings up the screenshot dialog, even if the print screen button is not the same as SysReq (which it is on some of them, but not all of them.)
Some preliminary details:
I have a (slightly) modified NW8440 laptop workstation made by HP in 2006 running Intrepid Ibex on a core duo, with an ATI graphics card.
I have a built from OEM parts desktop that was put together this new-years with a Core 2 Quad, 4 gigaybytes of ram, and an NVidea graphics card.
And earlier tonight I was at my friends place helping him set up Ubuntu on the desktop that he just recieved via FedEx, and this same command sequence had no noticeable effect, on either the Live cd environment, or the installed environment. I know his processor is AMD, but I don't know any other details than that.
Could someone perhaps direct me to where i could find useful information to append to this bug report?
Thanks,

Michael,
Thanks for reporting this bug, as it affects me as well.
I have only tried it on my home Desktop computer, a Core 2 Duo machine with an nVidia 9600GT (by Asus) graphics card, using the proprietary nVidia driver; a logitech Cordless Desktop keyboard and (optical) mouse (model Y-RAJ56A, with sysrq on the prtscr key); running Ubuntu 8.10 with all updates (but no backports).
I have also tried using the right alt key as "altgr" instead of the prtscr/sysrq key, as suggested at some sites (which I don't remember what the addresses were or how I got there...). Additionally, I have tried a number of other key combinations, such as leftalt+ shift+prtscr/ sysrq+k, to no avail.
I should note, however, that my TTYs are all functional (F1-F6), and respond as expected to alt+sysrq+ R/E/I/S/ U/B and alt+sysrq+K. It's only in the Gnome GUI that there is no affect, other than asking the user whether to save a screenshot. :-p
I have also tried setting different keyboard models (us105, Logitech Cordless Desktop [and "alternate"], and Logitech Cordless Desktop Optical), different combinations of "alt/win key behavior" and "compose key position" (in system> preferences> keyboard) , mapping "print screen/screen shot" to different key combinations (in system> preferences> keyboard shortcuts), and lots of various button mashing. :-)
Please let me/us (Michael et al) know if there's any further information that may be of assistance in solving this problem. With ctrl+alt+backspace disappearing in the next release, I think it's going to be important to get this resolved as soon as is reasonably possible. (Please note that I don't mean to put undue pressure on anybody by saying this.)
Thanks, Devs, for all your work; you make Ubuntu great!
