Mountain Lion Problems

unusedusername · 09-06-2012, 07:40 PM

I've found as a work around to this that if you enable disk encryption (Preferences->Security & Privacy->FileVault) that the normal login screen is replaced with one that does not get broken when DisplayLink is installed.

Just in case anyone is looking for a better solution then leaving the computer unlocked all the time.

Thats good to know and now I know why I never had this login issue everybody talked about. Full disk encryption is always on my stuff. Just have the lower resolution and graphical corruption on the secondary monitor in my cause.

Im using a MAC Book Pro, Core 2 Duo, so not the latest model but have upgraded with DisplayLink from Tiger, through Lion and now on to Mountain Lion. I use a Toshiba docking station and two USB adapters for a three screen solution at work (four with my MAC screen included). Basically the apps I use every day for business including Microsoft and Outlook all work fine. There is a very annoying bug in the 10.8 OS which changes random text to caps when entering phrases like 'I'm ' which is nothing to do with DisplayLink but other areas work fine. I had one issue with flickering in Safari which is when I have the option selected to show recent site images, but resetting this to not show the site image selection screen and default the browser to a given website overcomes this.

Not sure why I'm different or maybe people only come here when something is wrong but for me it's fine for work and I believe updates are coming likely from both Apple and DisplayLink given this is a new OS there are bound to be teething issues.

My screen is completely black - and I can't find the monitor in Settings/monitors. Seems like the installation doesn't work in 10.8.2. Anybody else having this problem?

I also have issues with the DisplayLink an am dissapointed in the lack of information listed on the "Works with 10.8 with these small issues" page.

I have an issue where my mouseclicks are about 1/8th of an inch off where the mouse is pointing, and windows are drawn about the same distance "off" For example, I can not see the + sign for New Tab in the Firefox browser.

I had flickering issues when playing videos before, but can not duplicate it right now, so will leave that as a "maybe Apple fixed it" mention.

I also will have the adapter not power up when I return after having the computer off for the night. I typically swap USB ports and it works fine for a bit before it happens again.

I would love to see more communication, not just buried 10 pages deep in this thread, would be willing to try beta drivers to see if they help. I just find it amazing that their has not been a single update to the driver for this device since July, over 6 months ago.

Displaylink is banking on Apple soon releasing 10.8.3 and hoping it fixes everyone's issues. My USB display has been sitting unused on the shelf for months now...

The issue is the same for me as described above:

Mac OSX 10.8.2, driver v.1.8, monitor is blank and does not appear in the Displays page in Settings.

Workaround is to uninstall the driver, restart, reinstall the driver, restart.

Very unpleasant. Looking forward to a prompt reply from DisplayLink!

RE: the screen flicker issue (ghost rectangles from the edges of previously drawn + moved rectangles).

I use SwitchResX. The screen flicker doesn't occur when I set the resolution of my main display at maximum (2880 * 1800). I have only seen the screen flicker on the main display, not the DisplayLink-connected displays.

Not sure if this has been mentioned, (didn't have time to trawl through this thread). Hope it might give a clue.

Good luck guys.
