I need to install Elementary OS on my (late 2009) iMac 11.1.
I am booting from an external USB and in when presented with a GRUB menu, I choose "Install Elementary OS" and then press e key to edit and add nomodeset and then I press F10 to boot.



With Elementary OS installed, I run into problems after rebooting. First I get GRUB to go in normal or recovery mode, I use nomodeset again to boot in normal mode but instead of the GUI, I get a command line and it asks me for a username/password. After that, I run startx and get a No screens found error. I think it has something to do with my graphics card driver (Radeon 4850HD).



Does anyone know how to get back to the GUI mode?

          Postfix configuration issue with fips on centos 7; mailgun relay

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
