(So I can't set nomodeset) When I select either Try Ubuntu without installing or Install Ubuntu I go to a light gray screen with a flashing cursor in the upper left corner.Īs with the DVD I've tried multiple settings in the bios and haven't found anything that makes a difference. Since I didnt have a usb, I decided to use Unetbootin to write an iso on my pc. Selecting that and hitting enter takes me to a submenu that only has the option to go back. Intrest made me switch: The first thing Ive seen that runs linux was Ubuntu. If you want something lightweight that doesnt have this issue, try Bodhi Linux or Linux Mint Xfce. When I try to boot from the USB thumbdrive, I go straight to a black Installer boot menu that lists options like, "Try Ubuntu without installing" or "Install Ubuntu". Kali Linux is for pentesters, you are not to install it, the documentation for Kali tells you this. I have used Xubuntu for years and also tried all the fixes but it either gets completely stuck booting and wont boot, or it boots very badly with a black screen for ages and a grungy flash of the logo then more black screen. I have combed through the bios making sure that everything I can turn off about quick boot or UEFI launching with legacy that I can find. These dots flash white to red, and then ultimately white to yellow, then the screen goes black. When nomodeset is checked I get a bit farther, it goes to a screen that says Ubuntu 14.04 with four dots under it. Ive searched around considerably, and it looks like I may need to set some. UEFI (its enabled, with CSM support), Legacy boot fails even harder. The display backlight is still on, the screen is just all black. Without using nomodeset I go directly to a black screen never to recover. Once I select an option (graphical install, install, try Ubuntu without installing.), the screen goes black and stays that way. I have tried all the options given in this answer. This is a follow-up to my original LiveCD, but as Ive done lots of updates since the last edit (and cant change the title to reflect that its no longer the Beta/RC1 of Mint 17. When I boot from DVD I get the purple splash screen seen in the first answer to this question (The thumbdrive worked on a different machine two days ago, so I'm pretty confident the thumbdrive is set up correctly.) You can make this a service and make the service start at the boot time. But depending on your Linux comfort level, this may be a little daunting. You can put your startup script in /etc/init.d and make it resemble to one of the existing scripts over there. I have tried both burning the iso onto a dvd and also using a thumbdrive. There are more than one way to accomplish this. Hopefully, that gets radeon (or vesa) to stop complaining about it and move on to actually starting up X.I'm trying to install Ubuntu 14.04 onto my new computer. Since a Mac doesn't have a BIOS, you need to a create a fake one and tell GRUB to load it at boot time ("loadbios" directive in the GRUB config). As the document mentions, this may be necessary for X drivers that are coded to read the BIOS for system information. I tried startx which started the x-server or x-window (not sure what its called) but it just brought up a black screen with my mouse cursor. Then press Esc, and press Enter to 'Try Ubuntu without installing.' You can also try acpi off and nolapic if nomodset also shows up as a black screen. I tried sudo apt-get install ubuntu-desktop but it fails. Press Enter and select English: Press F6, use the keys to go down to nomodeset, and press Enter. Normally I could get back to the desktop by pressing Ctrl+Alt+F7 but that doesnt work. If it is correct, then you may need to use the "dd" commands mentioned to create BIOS image files. When I start Ubuntu it enters tty1-6 instead of my desktop. Here's more info on that: … KMS_issuesĪnyway, I found this documentation helpful: … ding_Linux More importantly, I don't think it matters. I'm not sure if that would work or not (probably wouldn't). Enter the following commands: sudo apt purge gdm3 sudo apt update sudo apt upgrade sudo apt install gdm3 If it displays a warning, then choose gdm3 with arrow keys and press enter. I believe you can unload and then load the radeon module after boot and give it "modeset=1" to turn it on again. On Ubuntu 20.04, while you are in the black screen, you should do the following steps: Press Ctrl+Alt+F4 then login using your username and password. I found this thread while trying to solve a similar problem getting Ubuntu 12.04 to work on a MacMini 5,1 (Mid 2011) system.Īdding "nomodeset" (or equivalent) is necessary to avoid the use of KMS, which is only a problem for boot.
