Hi,

I have 8 button mouse of logitec , when I am pressing the 8th button of mouse , it crashes my Xserver in linux. Can any one help me to resolve this problem.

Not if you don't provide any useful details. There are MANY Logitech mice with 8 buttons, but you don't say which you have, or which button you're calling the 8th. You also don't tell us what version/distro of Linux you're using, what desktop environment you're using, or what (if anything), you've already done to define how the mouse works.

Ok I will update you soon

I am using RHEL 6.2 and mouse name is "Logitech Anywhere MX"

Great...and you still don't answer the OTHER relevant questions asked of you, which would let us help you. Since you're using RHEL, have you considered contacting Red Hat support?? You are PAYING FOR RHEL, right????

I did not find any answer on redhat support

You are STILL not answering the questions you were asked previously. Until you provide COMPLETE INFORMATION, no one here can help you. For all we know, you mapped the 8th button (or whatever you're calling the 8th button), to be CTRL-ALT-BACKSPACE, which WILL shut down the X server. Go back and answer ALL the questions you were asked, and post some relevant information from your X server logs.

If you're paying for RHEL support, then open a support call with them...they can diagnose things for you, and tell you what's going on at least. If they won't help you with the mouse, they can at least tell you WHY the x server is shutting down, which you can come back here and post.

Again, until you POST DETAILS and answer the questions you were asked, YOU CANNOT GET HELP.

ok sir
