I think you'll like Simplenote. It's attractive, fast and cross platform. I can see my notes on Linux, android, Mac, iOS and Windows.

Distributions / Ubuntu upgrade from 17.04 to 17.10
« on: Yesterday at 10:05:55 am »
I tried this today using an installation on an external drive. The upgrade was uneventful for the most part. Because I had been using a combination of Unity and Gnome with a bunch of extensions, I had to play around a bit to get my desktop back to what I had. Actually, with Unity, I couldn't because, although it still worked, the tweaks like changed icons wouldn't work from Unity Tweak Tool. With Gnome, I got more or less my old settings as default, but certain extensions there didn't work either. I had to play around a bit to get the default Gnome desktop of Ubuntu 17.10 working, but it did and it is nice. Fortunately the top icons I needed (dropbox, insync) showed up and worked on the top bar without the topicons plus extension. There is an update to that extension, but installing it and running it on the Ubuntu theme took away the dropbox icon. Turning off topicons plus and rebooting brought it back.

Upgrading to Ubuntu 17.10 stopped insync from working initially. You have to install sni-qt (in the Ubuntu repository) to get it working.

One other easily solvable problem was that the version of SimpleNote I had installed in 17.04 wouldn't work in 17.10. However, the snap version of SimpleNote does work. Good thing; I've come to depend on it.

Ubuntu 17.10 was released today, along with the other desktop flavours.

Jason, your messages are helpful nevertheless and I will look into the driver issue, though I am happy at the moment with using Mint. Incidentally, the newer display server is Wayland, and it might be relevant on Ubuntu 17.10 since it is the default. But Ubuntu 17.04 was still using Xorg.

More progress. I tried a bunch of acpi settings, and besides acpi=off, two other settings work in combination with nomodeset, though they still result in window effects. The two are:
Code: [Select]
acpi=noapic nomodeset
Code: [Select]
acpi=noapic acpi_backlight=vendor nomodeset
I tried both with a Ubuntu 17.04 installation on an SSD run externally. In both cases, boot-up was fast. In the first case, window movement was slow; you could see the delay effects when dragging or expanding a window. In the second case, window movement wasn't slow, but the animation when moving windows was lost. In other words, when you move or expand a window, you see only an outline until the action ceases; then the change shows instantly. But also in the second case, I lose the ability to change the screen brightness through "settings"; the setting to do so in "brightness and lock" is gone. I suspect that the missing brightness setting can be fixed with software. But I don't know the cure for the lose of real time window dragging effects. This is not a big deal, however, so I now have the possibility of installing Ubuntu on my 5k iMac. But since everything seems to be working in Mint, I'm probably going to stick with it now and continue to see how I can fix the window dragging in Ubuntu. Perhaps by installing the proprietary Radeon video card, as suggested by Jason?

I've made a bit of progress in getting Ubuntu to boot on my 5k iMac. Using Ubuntu 16.04, I can get it to boot right up when I use the grub parameters acpi=off and nomodeset. These parameters were actually recommended in one posting, but another suggested that nointremap would also boot and have none of the negative effects of acpi=off, so I hadn't tried that before. Unfortunately, while it does boot right up, window response is noticeably slow with these parameters; e.g., moving or expanding windows. Not something that I would be happy with. But at least I know now that a/the major reason for problems booting Ubuntu installers on the 5k iMac relates to acpi. I did try a few other alternative acpi options, but none except turning it off worked. But I don't really get why an acpi setting should relate to a 5k display, unless the problem is more the video card than the display. I wonder if I installed Ubuntu with the acpi=off setting and then added the proprietary Radeon driver if this would solve things. But what is Mint doing that's different because it works fine without the Radeon driver installed?

Speaking of Mint, dropping the default resolution to 2560x1440 does wonders for some of the windows. That's only half the resolution this iMac is capable of, but it's still darn good and I didn't buy that model specifically because of the 5k resolution. Maybe future distros will have kernels with native 5k capability.

Actually, I don't think Mint did because when I looked at drivers, it didn't register anything other than Intel Microcode. At any rate, assuming I found the appropriate one and downloaded it, how would I use it? Is this something I can deal with on the installer or something I have to add after a distro is installed? I'm not sure the latter would help since I can't even boot up a Ubuntu installer other than the 17.10 beta and the network wasn't functioning in the 17.10 beta.

Incidentally, even Mint doesn't give me the full resolution, though it did give me something halfway between 2560x1440 and full 5k resolution. This is a known problem with Linux on 5k and the resolution I get is quite good.

I didn't have any of those problems, and I'm pretty sure I had Synaptic working. I think it has to do with the display server. According to this thread, Synaptic works on Xorg, but in Wayland you need to issue a specific command to fix it and the fix only lasts until you reboot.

With reference to my SSD (not HD), I had problems with it running Ubuntu 17.04, so they aren't limited to 17.10.

Support / Forced convert to Linux Mint on a high dpi iMac

I've been doing a lot of buying and selling of my Mac equipment lately in order to get some more recent stuff, and my most recent purchase was a 27" late 2015 iMac, which I got by trading in an older one. This computer is really different though, because of its 5K resolution (5120x2880). I hadn't realized at the time that this might cause problems with Linux distros, but it does. I wanted to run Ubuntu 17.04 on it, but no dice - neither an existing installation or a live installation disk would boot.  I would always end up with a dark purple screen. I searched for solutions and came up with a few posts suggesting a change to the grub boot parameters (adding nointremap or nomodeset or acpi=off) would fix this, but it didn't. I tried Ubuntu 16.04 and got the same result, so I then tried some other distros as well as the Ubuntu 17.10 beta 2. The latest Fedora wouldn't boot at all, nor would Elementary. Clonezilla would boot to the first screen and then freeze. Ubuntu 17.10 beta and OpenSuse Leap would boot, but they would take 5 minutes to do so. I didn't try installing OpenSuse, but I did Ubuntu. It did install, and changing its grub boot parameter would allow it to boot up, but again taking many minutes. When it did boot up, network-manager would not connect to the internet with either ethernet or wifi.

I don't know if it matters, but this iMac is the mid-level one with the 3.3 ghz i5 and a Radeon R9 M395 video card; maybe that particular video card is more problematic than the default. At this point I was ready to tear my hair out, but I tried one more distro: Linux Mint Cinnamon 18.2. Changing the boot parameter to nointremap, it booted right up, installed OK, and the installation booted up normally once I permanently added nointremap to the boot sequence! I haven't been interested in either Linux Mint or the Cinnamon desktop for a long time, but I figured I'd better make this to my liking if it's the only thing that would work properly. I spent a lot of time customizing it to my liking, which basically means changing icons and making the panel look like Ubuntu Unity. Turns out that you can do this by adding a vertical bar on the left side of the monitor and pinning my most used applications to it. I can live with this! My only complaint is the lack of fine-grain magnification adjustment in Cinnamon; the only choices are default or 2x magnification for high dpi. (Ubuntu allows you to magnify to tenths.) But the 2x works for me.

Even though I'm happy with Mint, I'm still bugged about not being able to install Ubuntu. Others have been able to get Ubuntu to boot on a 5k iMac, so why couldn't I (unless it's the specific video card)? Mint 18.2 is a derivative of Ubuntu 16.04, so why should it boot so easily when 16.04 wouldn't boot at all? What is different about 17.10 beta that it can boot (though with a lot of stalling) when the previous version cannot? Also, I don't like the fact that I can't boot a Clonezilla disk on this because I use it a lot. I'm wondering what I can try to get Ubuntu and Clonezilla to boot from a live USB, and install in the case of Ubuntu. Might it work if I simply copied all of the grub boot parameters in Mint and use them with Ubuntu? I might try that next, but any suggestions would be welcome.

I tried a new install of Ubuntu 17.10 daily build on the Crucial SSD. At first it was OK, but fairly quickly I ran into problems that kept it from booting. I'm now convinced that this SSD is corrupted and I'm going to see if I'm covered by a warranty. Meanwhile, I pulled a different SSD out of a 2010 iMac that I'm selling to a colleague and put it in the 2011. It is working well with no problems.

I agree that it really looks nice; nicest implementation of Gnome that I've seen in a distro. I even like the wallpaper. The only thing I don't is the default icons. Changed them quickly to Flat Remix; the desktop really looks good with that being the sole change from Ubuntu's default.

Distributions / Ubuntu 17.10
« on: October 11, 2017, 06:45:47 am »
I downloaded and installed the beta 2 on my 2011 iMac. While I could have added back the Unity DE, I wanted to try Ubuntu's modified version of gnome. Been using it a week and I'm quite happy with it. The desktop is almost identical to that of Unity, and all the pieces work well together. My only tweak was to use the Flat Remix icons, which are now my favourites. All of my programs worked out of the box except Simplenote, which would install but not start up. However, there was a snap package for it, which does work. Ubuntu 17.10 actually feels faster than 17.04, but this may be because my 17.04 installations are upgrades on Ubuntu going back at least to 14.04. While still a beta, I haven't had any obvious problems with it so far. Has anyone else tried it yet?

Interestingly enough, the Ars Technica guy who wrote the article thought highly of the Windows OS and laments its loss. While I wouldn't buy one out of principle, the tile interface does make sense on a phone.
