[wlug] Ubuntu's reputation dented?

I've had a few problems since upgrading from Ubuntu 6.10 to 7.04 I'm still researching what to do about them. It seems I'm not the only one with problems. The ones I've got are: 1. USB flash drive is no longer auto-mounted. System message log notes insertion and removal. 2. System doesn't appear to recognise any media in DVD/CD drive. 3. Swap file has to be mounted manually. The last problem may go back to 6.10 ... it was because of that problem that I decided to upgrade. Seems that the swap file was corrupted a while back. Has anyone else done the upgrade? Did you experience any of the above problems? Michael
