Firstly I have to start by saying how much better Linux Mint 9 looks compared to other versions, and I do support and welcome the hard work of those involved in it's development. However, I have found some bugs or issues which could deal with been resolved - I am using a Dell Dimension with an intel chip set, one of the more common pcs in the UK market.
1) The Xserver Intel crash bug still exists.. but with a slight improvement, instead of the pc just hanging, it auto logs outs, or more precisely starts up a new login session.. but at least no hard reboot is needed, but still annoying if working on something when it occurs.
2) Unlike Linux Mint 8, unable to revert the Xserver Intel driver from version 2.9 to the bug free 2.4 version. You could revert it in Linux Mint 8 via Jaunty Repo, but if you try to do the same thing now in synaptic manager it says that it has to uninstall all of the Xorg, which is obviously something I do not wish to occur - so unlike Linux Mint 8, stuck now with a buggy Intel Xserver driver. If someone does know how to change it back to 2.4 please let me know.
3) Creating a new gnome panel - if I click on the existing panel, and create a new panel, no new panel exists.. instead a invisible, unclickable, window area appears.. but if you then logout, and then log back in again, the gnome panel previous created then appears.
4) Cryptmount - more annoying than a bug, the partition labelling appears to have changed in Linux Mint 9, so have to manually edit the cmtab files to modify for the new partition names.
5) But now for the really annoying feature, or more precisely a feature removed from Nautilus, unable to change the properties of the location bar - there doesn't appear to be anyway now of changing the location bar in Nautilus to a file location string rather than the fixed path buttons we have now. It can be changed in a file dialog box, but not in a fully opened Nautilus session.
Hopefully this will be resolved in up coming version releases, but issue 5), which appears to be a deliberate design change, totally baffles me why anyone would have changed it - it's reducing features, not increasing them. Reduces the productivity of Nautilus by a massive degree. Going to see if I can ditch Nautilus in favour of something more function-able.
