We’re not sure yet if we have a certain solution. There are apparently a few variations of the Lenovo W500 out there, with some different behaviors. From the msinfo output above, yours has both Intel and ATI graphics.
One thing we’d like you to try, if possible. Can you see if there’s a BIOS option to disable switchable graphics on the system? Here’s how Lenovo describes it (in http://www-307.ibm.com/pc/support/sit…)
Can I disable Switchable Graphics on my Lenovo system?
Yes, there is a BIOS setup option to disable Switchable Graphics. In the BIOS setup utility (press F1 immediately after powering-on the system, while the ThinkPad logo is shown), enter the Config menu, then enter the Display menu. Change the Graphics Device from Switchable Graphics (the default) to either Integrated Graphics or Discrete Graphics, whichever you prefer.
Also, if you are using Windows Vista, you must disable OS Detection for Switchable Graphics. If this setting is enabled, booting will re-enable Switchable Graphics. Booting any other operating system will only change the setting from Switchable Graphics to Discerete Graphics; if the setting is already Integrated Graphics, it will remain so.
Note that loading defaults in BIOS setup (shortcut: F9) will cause both of these settings to return to their default values.
If you are able to disable switchable graphics (hopefully running just the Intel driver), then try again to see if the DisplayLink driver flags any problems at install time.
If there is no BIOS option to disable switchable graphics, again just let us know.
From this test, we’ll figure out next steps.
Thanks for your patience!
