Most likely it is RGB, but you can check at http://www.lagom.nl/lcd-test/subpixel.php

For example to check if row 5 is visible use formula subtotal(2; A5:A5) - that will return 1 if row is visible, and 0 if it is not. It should work in Excel as well.

Important thing (if using regular expressions in server names configuration in NGINX) is to make sure to pass $host as SERVER_NAME in fastcgi_params - like:
fastcgi_param SERVER_NAME $host;


Default value of $server_name will pass regexp and that will cause Mono to crash while parsing request URI.

If you have to set native resolution on system console (if for example you have to run scfb driver for X), first check resolutions supported by UEFI - escape to loader prompt when booting OS and type:
mode
That should list all textual modes recognized by loader (alternatively you can also try gop list or uga list, but saving gop mode setting using following method won't work (I don't know about uga since my computer doesn't support it)). After this you can set mode you want to use using
mode NUMBER

Things to check:
That you have BusID in your Device section - syntax example BusID "PCI:1:0:0" (you can discover it for example using nvidia-xconfig --query-gpu-info or pciconf -lv). If you have problem with finding modes for monitor you can add Option "ModeDebug" "True" to your Device section in xorg.conf.

First find it with

$ mailq
/var/spool/mqueue (1 request)
-----Q-ID----- --Size-- -----Q-Time----- ------------Sender/Recipient-----------
w0MEs0vA055142 5289 Mon Jan 22 14:54
(Deferred: Operation timed out with some server.)

Total requests: 1

Then delete it using qtool.pl (in sendmail's contrib dir):
./qtool.pl -C /etc/mail/sendmail.cf -d /var/spool/mqueue/w0MEs0vA055142


cmake -DCMAKE_VERBOSE_MAKEFILE=on ...
