USB keyboard-mouse combo error (Logitech K220)

[Taarka]

Hi!

Preface
The PC I wanted to have TC on is an old AMILO Mini Ui 3520 notebook, which has a faulty built-in keyboard. There are only two USB ports on it so to have an external mouse (for convenience) and a working keyboard, I bought a wireless keyboard-mouse combo USB dongle (Logitech K220).

The problem
The keyboard part of the peripheral works without a problem, but the mouse has a weird issue. I can move the pointer and click on UI elements that expect a single-click interaction. However when I try to navigate the path selector dialog (where I have to double-click) it does not respond. It's like the second event is being dropped.
At first I ignored the problem and wanted to browse the filesystem in terminal, but after opening one I noticed that something is very wrong. If I click inside the terminal a question-mark character will appear. I guess some non-ASCII keyboard key event is fired along with the mouse event.

Troubleshooting

• I tried using a generic wired USB mouse and keyboard and those work without a problem.
• I removed the batteries from the keyboard part, but the mouse still did not work as expected. (I wanted to rule out some stuck key or similar issue)
• The keyboard and mouse work perfectly on other PCs (Debian, Arch and Windows), so the hardware is not at fault.
• The touchpad works correctly regardless of the peripherals being connected or not.
• I have not found a report/question about an exactly same issue online, but I've tried a few things suggested for similar problems: legacy USB setting in BIOS, psmouse.proto=imps...
• I wanted to see what events X is processing, but there is no xev utility...

Conclusion
I've had my fair share of hardware compatibility issues using a variety of distors, but never have I expected to get stuck at a not working "basic" mouse. I don't know what or how to debug to get ahead.
I'm looking forward to hearing some insight or any ideas really.

Thanks in advance,
Taarka

What version and architecture of tinycore are you using?

Are you using Xvesa, Xfbdev or Xorg?

[Misalf]

Are you using Xvesa.tcz? using Xorg-7.7.tcz instead may help.
xev is provided by Xorg-7.7-bin.tcz.

I've downloaded the CorePlus version of TinyCore this morning (7.2). It's the x86 architecture. So maybe it's not apparent from my original post, but I'm very new to TC. I wanted to fiddle around with the install and remastering tool to get a grip on how things work.
Xvesa is the first extension that gets loaded on boot, but I'm not sure how to check what else TC has loaded... /var/log is virtually empty.

How can I instruct TC to load Xorg instead of Xvesa?

[Misalf]

To download

Code: [Select]

tce-load -w Xorg-7.7
To make it the default, you can either use the Apps GUI or edit
/etc/sysconfig/tcedir/onboot.lst

Then reboot.

To learn how TC works: http://tinycorelinux.net/book.html

I exited to prompt and

Code: [Select]

tce-load -wi Xorg-7.7
startxnow mouse works correctly. Wow was this simple yet not evident at all? (maybe only for me...)

I'll keep the book close from now on as well. Many thanks!

Xorg is smarter than Xvesa.
