Random Thoughts

It's been a while since I've posted so this is an amalgamation of things that have been happening.  First of all, I now have a MacBook Air and the adjustment has been minimal.  All my Linux desktops have sort of been modified to have a quasi-OSX like setup with the arrangement of the close, minimize, maximize buttons.  At worst case, the terminal gives me back that Linux touch and gives me a lot of power back when OSX's UI fails me.

I love the touchpad gestures.  It's probably the most unique aspect of OSX.  Taking the cool computing ideas from Linux and giving it that Apple take on things gives me a good perspective on what can be done to make desktop computing more efficient.  That being said, I just really don't like the regressions that happened.

Getting my PS/2 keyboard with the USB converter to get recognized in OSX is mindbogglingly difficult.  I scoured multiple websites screaming at me the words: "No, it doesn't work." But I refused to believe.  It turns out that the solution is to turn off my MacBook and plug the keyboard in while the device is turned off.  Why?  I don't know.  If the keyboard is supported, why on earth would you want to make it harder to support such devices?

The USB ports are way too few and the Mini DisplayPort (Thunderbolt) really blows here.  Suddenly, I can't use the extra monitor sitting here and I have to buy some fangled adapter to get it going (It's on the way...).  Lastly, the SSD drive is way too small, but that's to be expected.

Despite all of this, I am at peace with the Mac.  It's a nice device and gives me more experience as far as using other computing environments.  All that being said though, my next laptop will definitely go back to Linux.

Next stop, I reformatted my HP laptop that was running Linux Mint.  To be honest, I had been very disappointed with Linux Mint's performance here.  By the time I reformatted it, it had slowed down to a crawl on boot and on GDM login.  It has never ever happened before in any Linux desktop I've used and I have gone through quite a bit.  I tried to analyze the boot sequence and the GDM login process but to no avail.  It was just pitiful to see Linux perform this bad.

I installed Linux Mint 17.3 and that was a mindboggling choice.  The boot was as bad as when I had the bloated Linux Mint 17.1 install.  I was willing to forego that to see what the desktop had in favour.  Secretly, I hoped it would just simply disappear.  When I setup fglrx, I noticed that running amdconfig wouldn't detect any proper supported GPU (Mine is Radeon HD 7670M) which prompted me to look for the xorg version.

Linux Mint 17.3 runs on xorg 1.17.1 which seems to be .1 version above the latest fglrx version from AMD's site.  So I figured I should just ditch this.  I went back and reinstalled Linux Mint 17.1 on the HP Laptop.  I also installed fglrx and not fglrx-updates (which didn't work the last time I tried it).  After running amdconfig, I am treated with the same error which boggled my mind.  I checked xorg and the version was 1.15.  So, NOW, I'm really confused!

I rebooted anyway and fglrx seemed to load right.  I installed cairo-dock and the rest of my usual setup and everything seems set.  For some reason, Linux Mint 17.1 boots up faster than Linux Mint 17.3.  As long as it doesn't bog down, I can live with this.

Speaking of fglrx, I was also reading up if amdgpu and amdgpu-pro will have support on my Radeon GPU.  I think 7670M is still Southern Islands and that support 'should' be coming in the future.  Cross fingers!

Missing Caption and Dialog Box Messages on Cairo-Dock

I've been using Linux Mint 17.1 for quite a bit and its configured to using the fglrx driver.  When I first installed Cairo-Dock as a way to emulate Ubuntu's Unity, there had been missing text and captions on several items in my menu.  It's bothered me but I've tolerated it for a long while till I had had enough and did some research on it.

This thread gave me a hint that this is a known issue and that setting the font may fix it.  The suggested font to use was Ubuntu Mono 12 but that didn't work in my case.

By right clicking the cairo-dock, you can configure the Dialogue Boxes and Captions.   You can set the custom fonts to use for both.  For my Linux Mint, the font that worked was Andale Mono 12.  Now all the text appears.

Flashplayer and Linux Mint

So a vulnerability was found on Flash that made Firefox disable the Flashplayer until people updated their plugin.  Adobe released an updated version of the last non-Chrome version of Flashplugin for the update but I seemed to be running into some issues with the browser not picking up the latest version.  So, what I did was re-download the latest version of Adobe flashplayer.  Then, I copied libflashplayer.so into /usr/lib/adobe-flashplugin/libflashplayer.so and /var/lib/mozilla/plugins/libflashplayer.so.  Then, restarted Firefox and checked the add-ons.  Finally the latest version was recognized.  Back to regular programming.

Random Thoughts: Samba, Cinnamon and Android Insufficient Storage Space Error

So I've been using Linux Mint a lot and there's been some adjustment.  I find Cinnamon to be a total regression to Unity's dock.  I've complained a bit about this but fortunately, someone pointed me to Cairo which is a decent replacement.  It's not as slick as Unity's Dock, but it's functional and familiar enough.  I just cannot go back to that old Start Menu, Taskbar thing.  Feels cluttered and useless.

While we're in the subject of Cinnamon, when the laptop wakes up from suspend or sleep, sometimes, Cinnamon starts acting very weird.  None of my mouse clicks the menus, Cairo's task switching doesn't really work.  The only way I got to recover from it was to kill Cinnamon.  

killall -HUP cinnamon

Then, there's samba.  In the university I work at, we have some specific configuration and Cinnamon's connect Windows Share interface is a bit wonky.  Turns out when I specify the server name, I have to leave out the slashes (e.g. //).  Then specify the share to use.

Lastly, there's a common problem on Android where the storage space is always running out.  This usually manifests itself when attempting to install apps.  Google Play Store will complain "Insufficient Storage Available" which is a real pain especially when you own those Chinese OEM tablets.  I've learned since that Android will build up junk cache over time and can easily chew up GB of space after prolonged use.  You can use any cache cleaner app and run your device through it.  I use the Clean Master but I'm certain there are better lightweight apps available.  I ran my cleaner app and it showed me the junk I should clean up.  Tapped clean and I was able to install the apps I wanted just fine.

That's a wrap!  Ciao!

FGLRX Issues and Linux Mint

After installing Linux Mint 17.1 on my HP laptop, I noticed that the fglrx-updates package doesn't detect my AMD display drivers.  That's very disappointing but there's no release notes for the Catalyst driver yet (15.3?).  So, I'm not certain if AMD is supposed to drop support for the 7xxM series.  To install fglrx, I had to use the regular fglrx release from Linux Mint.

Then, of course, the Ubuntu fglrx issue dual monitor hit me hard with the flickering desktop.  Sheesh.  From my additional research however, I've found this blurb from the Arch Linux article.

When using a PowerXpress laptop in AMD-only mode (ie, setting the discrete card to render everything) you sometimes run into issues with artifacting/duplicating between displays. This is a known issue, and seems to effect 7xxxM series cards.
The artifacting disappears when you transform one of the monitors by either rotating or scaling. So you can use xrandr to fix this

So, I used the xrandr command they supplied and massaged it to my own case and came up with this:

xrandr --output LVDS1 --primary --mode 1366x768 --pos 0x0 --scale 1.0001x1.0001 --output VGA1 --right-of LVDS1 --scale 1x1 --mode 1024x768

This is not quite what I was hoping for as the second screen seems to display one half of my first monitor display.  After playing around with xrandr, I found the command that would fix it here.

xrandr --output LVDS1 --primary --mode 1366x768 --pos 0x0 --output VGA1 --right-of LVDS1 --scale 1.0001x1.0001 --mode 1024x768

The other caveat on Linux Mint seems to be the installation of the bcm4313 drivers, but that's easy to resolve.
