I have to mention I'm currently using a Samsung R-580 notebook with Intel i5 CPU, 4GB RAM, nVidia GeForce 310M video card.
That said, here's the current list in a somewhat random order:
• Without an Internet connection driver manager takes minutes to open up, and when it finally does it simply says: "Drivers cannot be installed. Connect to Internet or insert DVD/USB stick." One can't even see what drivers are currently installed and enabled, if any.
• Driver manager does not follow the currently enabled theme. (fixed in v1:1.4.4~gm10 at gm10's PPA)
• Express data card devices for 3G Internet (Huawei E3735, more precisely) do not appear in Network Manager although card insertion/removal is recognized and LED flashes correctly waiting for a connection. They only appear as CD drives in Disks. It takes a reboot to have such devices appear in Network, and if card is removed and reinserted it takes another reboot to see it in the Network Manager.
• Virtual CDs built into Express Data cards and USB 3G sticks are not recognized as valid data media and cannot be mounted to retrieve any possible drivers. Contents appears as Unknown in the Disks utility.
• The Network panel, if already open, is not updated in real time when a network device (USB 3G modem, Express Card) is inserted.
• There is no way to set up separate names and settings for Internet connections on the same device according to the current subscription card inserted in the device (although each card must have its own serial number or something). This creates major confusion if connection shows up as Provider1 while the card inside is from Provider2, and more so trouble when one is a metered connection while the other isn't. There's also no way to create separate profiles for different Mobile Broadband network devices, nor a way to connect more than one such device at a time and select which applications/services use a certain connection.
• The 3G connection randomly disconnects and most of the times it does not reconnect, either automatically or manually until the device is physically plugged out and back in; this doesn't work for Express Cards though, which once disconnected are not recognized by the system until a reboot (Hello Windows-Linux!)
• There is no option to NOT sort the desktop icons in ANY way but leave them EXACTLY how they are, aligned to grid or not.
• In a multi-monitor environment on a notebook, closing the lid automatically moves the desktop to the external monitor although nobody asked it to; moreover, when lid is subsequently opened, any and all application windows that were opened (minimized or not) will remain or open on the external monitor even though they were all initially opened/located on the internal monitor. Plus certain icons (launchers) will simply dissapear after this lid operation and only a system reboot will bring them back, unless the "Show icons from missing monitors" and "Show desktop icons on all monitors" are enabled, in which case ONLY the missing icons will be found on the external monitor. Personally I don't want second option enabled, and it's broken anyway.
• Sometimes closing the lid (with only built-in monitor enabled) sends the machine to sleep mode although settings are to DO NOTHING (both on battery and on AC) AND power management is disabled either by an application or manually (through the Inhibit applet).
• The Display panel is disconnected with the nVidia driver and its settings. If multi-monitor is set up in the nVidia driver, the system won't acknowledge it until the user fiddles with the Display panel too, and even there resolutions will apear bogus (1024x768 instead of 1680x1050 for external monitor, in my case).
• If one tries to set up dual monitor as separate
X screen 0and
X screen 1in nVidia driver settings, Cinnamon will crash.
• Bluetooth audio randomly disconnects from the headphones (Panasonic RP-BTD5 and RP-HF400B) minutes after connection, switching back to built-in speakers; sometimes BT connection is restored to headphones after a few dozen seconds, other times is not, leaving it to the user to try and reconnect. Moreover, there is no way to manage multiple BT adapters unless Blueman is installed. This notebook has an internal Broadcom adapter, an Intel one built into the wireless card and an external one from CSR, which is what I always want to use; I manually unplugged the Broadcom but the Intel cannot be permanently disabled (although wireless IS disabled) and Mint would never try to use the CSR unless Blueman instructs it to do so.
• Display brightness function very seldom works; it usually doesn't, although the OSD appears on the screen and slider moves according to the keys being pressed (Fn + Up/Down).
• Default file manager Nemo does not refresh folder contents in real time if file operations were done externally (i.e. creating a folder and downloading into it through the web browser). There is no Refresh option in the context menu so such folder appearing deep in a tree view cannot be updated and opened other than jumping directly into it, and then going back upwards sequentially.
• In Nemo there is no [Open/Edit/Run] as Root option for files, which complicates otherwise easy operations.
• There is no option in Nemo to only display detailed size (in bytes) - it's either compact or both, which is impractical and wastes too much column width.
• When a 3G (or possibly a Wi-Fi) connection with high priority is already active and wired network with low priority is enabled (or LAN socket is plugged in), system automatically redirects all traffic to LAN although there may be no other shared Internet connection on other computers. Result is all web-related applications will cease to work. One simply cannot be connected to LAN (for file operations between computers) AND have web-related applications working at the same time. Yes, "Connect automatically" is enabled, but do not blindly redirect unless there is a valid Internet connection through that LAN, even if "Use this connection only for resources on its network" is disabled.
• Desktop does not react on changing icon size.
• How does one set up the system to act as a DHCP server in order to use a LAN-connected printer (i.e. Lexmark E352dn) which has a fixed IP ?
• How does one set up notifications in order to avoid duplicates, as with Evolution, for example ? These are not the only problems I encounter with my Mint installation but are those that annoy me most lately. In time maybe I'll modify this list, adding or deleting items according to what happens in future Mint patches and/or releases.
If any of the developers cares to fix some issue or needs more info, please feel free to contact me by PM.
