That probably doesn't mean anything. The firmware can choose to handle the mouse in any way it wants, but the interface actually provided to the boot loader through EFI is more limited. The UEFI spec mentions x, y and z axis for a pointing device and recommends using z-axis for scrolling, but I don't know if the mouse wheel would be used as a z-axis, or just button 4 and 5 (which uefi doesn't do, only left and right). -- Len Sorensen ___ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel

If 'standards' have carried through from xorg.conf / mousedrv, buttons 4 and 5 would be wheel buttons. Button 4 is the default for "which button must be held down to enable wheel emulation mode."

Mouse support for just the wheel and left button.
Hello and thanks for Grub. I use it daily. I've seen questions regarding mouse support, but the answers imply that an on-screen pointer is requested. I would find it very useful to be able to use the mouse scroll wheel (which is just two switch clicks if I understand correctly) to move up and down between entries, and one click on the left mouse button to emulate pressing Enter. All that would seem necessary is for wheel up-button to do up arrow, wheel down-button - down arrow and left-button - Enter. I have my own reasons for wanting the feature, but, while searching for information, I saw that some users are finding their USB keyboard isn't supported and they may have found simple mouse button and wheel support useful. It could also help those who usually use on-screen keyboards like the quite excellent OnBoard. -- I've joined the list, so no need to CC, thanks. ___ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
USB mouse support, patch against trunk.
Hi, This is a patch for usb mouse support in GRUB. I cannot take credit for the code. It was written by a former colleague of mine (Christer Weinigel). Added some cleanups and a bugfix. It should be usable as is for most standard protocol mice. Regards, Christian mouse.patch Description: mouse.patch ___ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
Basic mouse support (cursor)
Over the past few days, I've been hacking on GRUB, and implemented mouse
support in the form of a virtual keyboard. That is when you move the mouse
around it generates arrow key presses or enter on clicks.
The attached patch is based on current bzr trunk (4559) and also fixes a
build error with a missing file (reported here:
http://lists.gnu.org/archive/html/grub-devel/2012-07/msg00042.html).
I implemented it as a module (based on at_keyboard), so the patch only adds
the c and h files and adds it to the modules list. Once compiled and
installed, load the ps2mouse module, and run terminal_input ps2mouse. I
highly recommend NOT doing it in your grub.cfg* until you verify it works
since it implements its own ps2 keyboard driver (99% copy and pasted from
at_keyboard). Once you've set the input to ps2mouse, you can use the mouse,
but by default it only allows up and down movement. To enable all movement,
run mousectl enable x. Also disabled by default is clicking; enable with
mousectl mousemode. Since I didn't hire multi-million dollar user
studies, the threshold for movement may require some changes to suit your
liking. Luckily, its easy to fix with mousectl sensitivity y someNumber
or mousectl sensitivity x someNumber (defaults are 20 and 12
respectively). The mousectl command has a few other features, so check
the help or source.
I know the source needs a bit of cleanup, but this is the first revision.
Any feedback is appreciated. I've tested it in QEMU and on real hardware
(wireless usb mouse actually), and only bug is a spurrious right click
occationally (which goes to edit mode). I'm currently using this on my
computer that has about 30 boot entries, and I really like it since I don't
have to hit the down arrow 30 times.
*While testing, I used this entry that I found useful:
menuentry 'Load mouse' {
terminal_input ps2mouse
mousectl mousemode
}

Mouse support in GRUB
Hi GRUB devels, recently I came across the improvements made by Microsoft Windows 8 in their bootloader. http://blogs.msdn.com/b/b8/archive/2011/09/20/reengineering-the-windows-boot-experience.aspx However I despise the operating system itself ( :-P ), the idea of a beautiful graphical bootloader with mouse support integrated into it felt amazing to me. It lowered the barrier for the user, and gave the user an at-home experience right from switching on the computer. I wanted to check if something similar can be done with GRUB, and found out about the gfxmenu that was merged in 0.98. I think it is a great step forward, and would be a really nice addition to all major distributions in near future. However, I think that the graphical menu is somewhat incomplete without mouse support. So I wish to work on implementing mouse support for GRUB. However, I am a novice to the GRUB codebase, and need some help with understanding the relevant parts and with testing my implementation. I myself have done a little bit of reading, reading the source code for the term module which implements the keyboard support into GRUB, and have more or less understood it. Also, I read up the HID specifications document for USB devices. It would be really wonderful if someone with experience with the relevant code can help me by guiding me when needed, and help me with a few of the problems i am facing with testing my build of GRUB with qemu. -- Regards Tirtha Chatterjee KDE developer http://wyuka.co.cc/ ___ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel

This is not an easy task. Unlike keyboard mouse needs to be either polled pretty quickly or used with interrupts. Also it will mean that you'll need to adjust graphics driver to show the cursor and to move it quickly bypassing the usual core. Only the events like mouse clicks should go through something like grub_checkkey or grub_checkkey itself. -- Regards Vladimir 'φ-coder/phcoder' Serbinenko signature.asc Description: OpenPGP digital signature ___ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel

I I don't think the user needs to feel exceptionally home at the bootloader so long as the bootloader does its job well - boots the system asap. I agree. Also using keyboard is much faster and precise in this case and doesn't need any additional knowledge. So entry barrier talk is a nonsense.

So I wish to work on implementing mouse support for GRUB.
I've attached the result of my early fidling with grub on sparc.
Yeah, once I got grub to load, I made a serial msmouse work instead of working
on things like actually getting it to boot any OS.
It most certainly won't be applying cleanly on current code, and it is highly
unlikely that I rebase it myself.
This adds 2 modules to grub, each with a single command.
Both modules require ieee1275, and were only tested on sparc.
One opens a serial port and moves a mouse cursor on screen. It doesn't
integrate with anything (no event system...).
The other draws a mandelbrot fractal (this is off-topic, but it was in the
same patch...).
More seriously, I feel the only value in this patch is in the ieee1275
wrappers for framebuffer entrypoints.
If anyone feels like integrating any chunk, please do. I had signed the
copyright assignment back then, so you can consider the FSF own copyright on
that patch already, as far as I'm concerned.

Mouse support
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I added basic mouse support for ieee1275. It's really, really basic : - -Only works with serial mice - -Only works with Microsoft 2 buttons protocol (might work for 3 buttons without wheel) - -One has to set the serial speed from OpenFirmware command line - -I only use what the mouse give me : button pushed or not, x y deltas (nothing like [double] click handling). - -For some reason, the mouse is very choppy, like 3 updates per second, and it sometimes has strange moves - but I guess the second is because it's an old, old retired mouse. And for now it doesn't return (I should add a key press detection or something...). I'm writing a clean patch to add both Mandelbrot mousetest commands - IEEE1275 only for now.
