MacBookAir i7 OSX Lion Performance Woes
Hi, I've tried the latest beta drive 4, but my MacBook Air i7 still suffers a considerable slowdown even when the 2nd monitor is disconnected.
The only solution being is to uninstall the driver. Is it possible to have the installation/uninstallation process not require a system reboot. Or at least deactivate the driver to avoid slowdowns when the 2nd monitor isn't plugged in? Please? Thanks, Ash |

I'm considering getting a MBA + two USB screens -- could I ask for more details from you?
-- Did you resolve this issue already? -- Can you list all of the displays that you have connected and when the slowdown occurs? e.g. It sounds like: (1) MBA Attached Display (2) Display connected via thunderbolt/VGA (3) Display connected via USB <-- Slowdowns happen at this step -- or was it: (1) MBA Attached Display (2) Display connected via USB (3) Display connected via USB <-- Slowdowns happen at this step -- Eddie |

Hey Eddie, It's a pure install driver issue.
If I have no external monitors attached, it runs slow. As soon as I uninstall the driver, my MacBook Air runs fine. |

Confirmed

Update: But! Just installed 10.7.2 and it seems significantly faster. I’d call it near-native speed on my primary monitor, and not too much worse on my DisplayLink screen. Things are looking up. Last edited by cshbell; 10-12-2011 at 07:43 PM. Reason: Updated info. |

Like several others, I've been forced to uninstall the DisplayLink driver entirely to regain reasonable graphics performance. Once the iOS 5 update rush abates and I'm able to install the 10.7.2 update, I'll give the driver another try and report back. |

10.7.2 seems to have resolved the issue. Obviously we're never going to see performance comparable to a hardware GPU with a simple USB adapter and software display driver, but I'm back to using dual 22" displays with my new MBA, and the performance is quite acceptable.

Okay, 10.7.2 isn't a complete fix. I've provided more detail in the other thread linked in the post above.

Just tried the new Beta 5 drivers and my MacBook Air runs a lot faster compared to the Beta 4 driver.
Thanks for the improvement. |

MB Air does not work
With the new beta 5 the second display on my MB Air does not work any longer. It just stays black. Attached is one Apple cinema by the display adapter and another over USB. With the beta 4 it works, but slow.
I already tried to uninstall and re-install the drivers but without any effect. only re-installing Beta 4 brings up the screen again. |
