I installed Debian Testing about 3 weeks ago on a Dell Inspiron 2650 laptop and everything was working fine. I did a netinst with LXDE desktop and even plugging in my Dell 2 button wheel mouse worked. It has the 2.6.26 kernel.

Today I did a safe-upgrade and now the mouse is not working at all. The touchpad continues to work. I normally boot with the mouse plugged in.

When I run dmesg | tail, I see 'New USB device found' after unplugging & re plugging the mouse in the port.

Any ideas how to get this to work? My /etc/X11/xorg.conf is empty but everything else is working as normal.


I just plugged in a usb thumbdrive and it is detected and automounted.

Thnx.

You could try to create a xorg.conf
take a look at
http://www.linuxquestions.org/questi...g-file-743438/
for a guide

It's a bug in the new xorg

I did add a xorg.conf file and adjusted the mouse section but still not working. I guess I'll have to wait on a fix but I sure hate using the touchpad instead of a mouse.

Thnx.

You could try to disable synaptic section in xorg.conf
and add the conf for usb

I've tried what you mention, repo, but still no mouse. I've also tried with /dev/input/mouse and no go. I'm not sure what the problem is. It just seems odd the mouse would stop working, even though it listed as a known device using lsusb.

Thanks, I appreciate the help.

I have the same issue; however, this happens to me on my desktop, so I have to reboot to use my mouse again I'm trying to reinstall with a different method to see if that helps me... Good luck, I hope there's an answer to fix it completely, soon. I'm not sure if reinstalling will even fix it

Rebooting is not fixing this issue with the laptop, I'm not sure what the problem could be. I guess some type of bug somewhere came up. It is these types of small issues that distros should not be having. Maybe a fix will come with the next update of X or the kernel.

It looks like I am experiencing the same problem (using Fedora 11 on a Dell Dimension 5100 Desktop). All was working wel until I installed updates using yum (I do this once a week and had been working without problems so far). I can see the mouse pointer in the center of my display, but no matter what I do it won't move. I booted Fedora Live and all was working again so I guess it is not a hardware problem. If someone has a solution for this problem I would appreciate it if they would post it. As this problem seems to occur on both Debian and Fedora it is probably generic and not distro related.

Hello again. After some research I found out the problem is caused by bluez (Bluetooth stuff). I replaced the bluez packages that were updated by the original ones and now everything works again (although I had to reboot my system first). I do not have a Debian system here, but chances are your problems are also caused by updating bluez.

BetelgeuseFive, I'll look into it. I did a netinst with Debian, meaning a minimum installation, I don't think any bluez stuff is installed. I will check to be certain, thanks for the info.

But Wednesday I installed Pardus Linux and after installation and first reboot to login, the usb mouse is not working. It uses KDE and may have the bluez.

Thnx.

I have a similar problem. Debian Lenny, kernel 2.6.17. Here is my sources.list:

deb http://ftp.uk.debian.org/debian/ lenny main contrib non-free
deb-src http://ftp.uk.debian.org/debian/ lenny main contrib non-free
#
deb http://security.debian.org/ lenny/updates main
deb-src http://security.debian.org/ lenny/updates main

I did apt-get update; apt-get upgrade and this seemed ok but the X server failed with this error:

(EE) AIGLX: Screen 0 is not DRI capable
(EE) xf86OpenSerial: Cannot open device /dev/input/mice
No such file or directory.
(EE) Configured Mouse: cannot open input device
(EE) PreInit failed for input device "Configured Mouse"
No core pointer

I gather from an LQ post that the DRI error will not stop X working so the mouse error is the
important thing. I tried mknod /dev/input/mice c 13 63 and tried startx and the error changed to

(EE) xf86OpenSerial: Cannot open device /dev/input/mice
No such device.
(EE) Configured Mouse: cannot open input device
(EE) PreInit failed for input device "Configured Mouse"
No core pointer

so I was not much further forward. Like Fred, lsusb knows the mouse is there. And like Fred
I am a bit annoyed; all I did was an upgrade. This desktop has a second disk so I just cleared
the rubbish out of that and installed Debian Stable on it from an ISO CD. So I have a working
system again, with a mouse obviously, and after a few hours work I shall have all the applications back but I'd still like to know what was wrong. I still have the original system
on the first disk so I can do some diagnostic tests if you can suggest any.

haha... sometimes linux can get very childish.... i am new to this (novice).. i had a problem with linux not recognizing usb mouse... after coming here... i disabled bluetooth/wireless connection, connected mouse to the laptop... mouse worked! and i put the bluetooth/wireless connection back on.. and it worked too! what a childish play... for a record... i am using linuxmint 11
