Hi Guys,

I've some problem with my cursor. I got the 64-bit version, fully updated.

Here are some specifications:

Model: Lenovo Thinkpad X1
CPU: Intel Core i5 2520M 2,5 GHz
Graphics: Intel HD Graphics 3000
HDD: Samsung 830 Series 280 GB SSD
Memory: Corsair 8 GB DDR3 SO-DIMM RAM

Installation: Through USB

The cursor freezes bitwise, when moving it around...

Are you using a usb mouse or wireless mouse? I know that my wireless mouse work perfect but some times it's slow.. when that happens I change the battery and then it works fine.

Have you ever tryed 32 Bit version?

The implementation of intel CPU is not really 64bit, is a kind of pseudo 64bit and does not works everytime as it should on 64 platform OS.
So, you should try to install the 32bit version and if it gives the same problem we will be able to work on it and give you some advise.

Have you ever tryed 32 Bit version?

ps: Welcome dear!!

My model does support 8 GB:

Multiple Display   DVI + LVDS, DVI + HDMI, HDMI + LVDS

I'll try to install the 32-bit version instead... But as I've understand it does not make use of all the whole RAM? Can I do anything to come around this?

It's a laptop so I use my touchpad. But I can try to use another mice, if it's a case about the driver. Thanks for the idea.

try the 32 Bit and look if it can manage ram without trouble... anyways there are some workaround, like here http://www.cyberciti.biz/faq/ubuntu-linux-4gb-ram-limitation-solution/ or just googling a little :) . So, i'm luky and my bbox works out of the box!

I think you could be wrong about this. You say this "implementation" does not support real 64bit. But did you emanate, that I don't got the same motherboard as weVeg mention? Thinkpad X1's are made with many different models like many other manufactory lines. My chipset does support SandyBridge, but I got no idea if the one WeVeg got supports it. Could maybe be relevant? Is it still pseudo 64bit? I might say that I've now tried the 32bit version and the problem consists...

Please check my specs again:

I think it's lacking compability... But maybe I'm wrong. :)

EDIT: BTW, I got Windows 7 Enterprise 64Bit and it works perfect. It's beeing delivered with 64bit Professional...

I can be wrong for sure, but the fact is, in my knowledge I know that real 64bit intel cpu are xeon and/or itanium stuff...
with this I mean, in this case a CPU might have external data buses or address buses with different sizes from the registers, even larger. The term may also refer to the size of low-level data types, such as 64-bit floating-point numbers but not instruction set. It was a long and old discussion that we had somewhere else in community wide, I don't remember now the details....but anyway, let come back to your problem.

I think it's lacking compability... But maybe I'm wrong. :)

EDIT: BTW, I got Windows 7 Enterprise 64Bit and it works perfect. It's beeing delivered with 64bit Professional...

Can you check the X log files and the system logs as well if there are any suspicious logs related to pad?
Because I have a lenovo (l420 64bit) as well with similar specs of yours and haven't noticed any problem regardless.
Could be pointer problem in x configuration file.

I can be wrong for sure, but the fact is, in my knowledge I know that real 64bit intel cpu are xeon and/or itanium stuff...
with this I mean, in this case a CPU might have external data buses or address buses with different sizes from the registers, even larger. The term may also refer to the size of low-level data types, such as 64-bit floating-point numbers but not instruction set. It was a long and old discussion that we had somewhere else in community wide, I don't remember now the details....but anyway, let come back to your problem.

Because, my knowledge about the technical parts of the architecture are limitited, I bet you got more chance to be right in this case. I know basic stuff about hardware architecture, like how data representation works, how some logic gates works, how FSB and QPI works etc. I don't know how SandyBridge works in detail or how the representation of the 64bit functionality works. So my mistake...

It does not only freezes bitwise, there are also problem with the buttons. Pressing the left button, means the right button quite often. So I think it could also be related to the drivers... just a guess.

The logs are looks pretty normal as it recognizes touchpad....
Digging around I have noticed that lenovo suggest the thinkpad own drivers instead of standard Synaptics.

Have a look here and try it: http://www.thinkwiki.org/wiki/UltraNav

If it doesn't fix, we will figure out in different way ;)
