Laptop touch pad problem in linux mode

Dear all,

my laptop touchpad doesn't seems to work in linux mode while it is working in win7 mode.I think i need to install driver for the same.but how should i go for it? plz help.


Regards,

Please define "linux mode". :?: What model laptop & Linux distribution are you using? How is the touchpad named/identified in Windows? (control panel -> device manager, or Win7 equivalent of that).

actually i have both win7 and rhel6.0 installed in my laptop.while booting through win7 touchpad works fine, on the other hand while after booting through rhel i have to use mouse for everything and pad doesn't work.

my laptop is of Sony Vaio.

regards,

Can you please provide more details? Like:

• Exact laptop model (not just vendor name).
• When in Windows device manager, how's the touchpad device named? (again: manufacturer and type). Also useful would be if you could tell through what bus it's connected (PS2? a PCI device? internal USB port?). Most of this info should be visible in Windows' list of devices.

In RHEL, you might try this: open a terminal, type "dmesg | grep -i touch" (without the quotes). Not foolproof I think, but that shows how kernel detects touchpad device on my own laptop... :smile: So if that returns anything, please cut & paste here?

Check /dev/input/ for mouse0, mouse1 devices to see if kernel has detected the mousepad or a regular (plugged-in) mouse? And/or check Xorg log file (/var/log/Xorg.0.log here, might be another file in RHEL) for references to mice / touchpads. If you had an external mouse plugged in: does the touchpad also not respond when you disconnect that mouse? Possibly the touchpad is detected by the kernel & working just fine, but Xorg isn't using it due to a configuration issue or so.

Hi,

Laptop model: VPCEH15EN/B/W :Sony Vaio
Device Manager- Mice and other Pointing Device-(1)Alps Pointing-device for vaio,(2)HID-complaint mouse

Output of RHEL terminal:

[root@localhost Desktop]# dmesg |grep -i touch
[root@localhost Desktop]#

it didn't give any output atall.


Regards,

Try Googling, for example for "VPCEH15 vaio linux touchpad" (just the words, without the quotes). Results suggest a number of possibilities:

• Perhaps there's a hardware key to activate / de-activate it? (on my own laptop, it works like that for wireless networking - nothing goes until I tap a button above the keyboard).
• Perhaps it's mis-detected as a PS2 mouse?
• A newer kernel version might fix/cause failure of the auto-detection.
• Creating / editing an xorg.conf file might make it work.
• ???

Unfortunately it's rather difficult for me to see what's happening... :sad:

Hi,

Firstly,I'm using rhel 6.0 (32-bit).Isn't it the latest version?
Secondly, would like to know as how to create/edit xorg.conf file.
Thirdly, i could not understand the meaning of PS2 mouse (this might sound stupid but truely i dnt know the meaning of the same, hence would like to know from u plz).
