Description of problem: I'm trying to use the full version of the install ISO on my laptop. To start with, the boot screen only covers a portion of the screen. No worries there, though. I can see it and I've had this happen with others (including the Mageia 7 Live DVD ISO). The problem is when I press enter to start the install of Beta 1, the screen scrambles (like it's trying to use the wrong resolution or something) and never recovers. Version-Release number of selected component (if applicable): Issue occurs (for me, anyway) on both the Mageia 6 and Mageia 7 Full Install ISOs. Issue does not occur using any of the live ISOs Screen I am using is a 1366x768 laptop screen, Intel graphics How reproducible: Happens every time I boot Steps to Reproduce: 1. Boot to full ISO bootloader (UEFI) 2. Press Enter to boot 3. Screen garbage Please see https://www.reddit.com/r/Mageia/comments/aio04r/mageia_7_full_install_graphical_issues/ for a screenshot of the issue.
Have you tried with a live image? Please give more details about your hardware
It is not clear to me: is this during install or after install and reboot? Can you then hit F2, F3, F4 or Alt+F2 etc and get some text screen ?

@katnatek Live image has no issues. Boots fine, loads fine, installs fine (though the mirrors are missing a few things I need, but that's unrelated to this). Hardware: Dell Inspiron 15-3521. Intel core i3 processor, Intel graphics. Cheap laptop that I've owned for a few years. Let me know what more you need. @Morgan Leijström This is after the install ISO boots from the initial bootloader screen. I cannot hit anything to get any text. There is something that comes up in blue on the screen during the boot process, however I am unable to read it at all, only see that part of my screen turns blue.
One difference between the installer ISO and the Live ISO is that the installer ISO just uses the EFI frame buffer, whilst the Live ISO loads the device driver for your GPU and uses the frame buffer it provides. At the installer boot menu, press 'e' to edit the boot command line, change "vga=791" to "vga=788", and press Ctrl-x to continue. If that doesn't help, try again, but just remove the "vga=791" entirely. If neither of those helps, does your laptop allow you to boot in legacy mode? If so, does that get any further?

Assigning to Martin, because he understands what's going on. @ Martin Feel free to reassign if you don't agree.

@Martin: "At the installer boot menu, press 'e' to edit the boot command line, change "vga=791" to "vga=788", and press Ctrl-x to continue. If that doesn't help, try again, but just remove the "vga=791" entirely." vga=788 does not work, removing the comment entirely also does not work. I also tried "xdriver=free" from the Live ISO, but that also does not work. I finally tried replacing the entire boot string after "vga=" to that of the Live ISO and there was a menu of some sort that came up (graphics still scrambled over the top 2/3 of my screen so I couldn't read anything, but pressing the up/down arrows did move something red on the screen). "If neither of those helps, does your laptop allow you to boot in legacy mode? If so, does that get any further?" It does allow Legacy booting, but every other distro I've tried has booted just fine with UEFI on this same hardware, and the Live ISO also boots just fine on the same hardware. It seems like it's only the 6 and 7 full ISOs that don't like it.

Legacy boot will use the legacy framebuffer, not the EFI framebuffer. This problem doesn't occur on any machine I possess, so I can't debug it by myself.
Legacy boot *does* work and the installer comes up as visible.
There is a small change to the way the ISOs boot coming in beta2 - let's see if that helps.
beta2 ISOs have now been released - do they work any better?
The installer is slightly weird with the resolution on my laptop (native 1366x768), but it *does* come up now and appears to work perfectly with the Beta 2 full ISO.
I'd expect the aspect ratio to be wrong on a 1366x768 display, but nothing more. Could you capture a screenshot to show what you mean (press F2 when running the installer - the PNG file should be available in /root/drakx after installation).
https://imgur.com/a/xn6xbnR You can see the black line running down the right side, but the language selection in the installer itself runs into it. Weird, as I said, but not a breaking bug by any means. The line in the first screen also appears in fedora and OpenSUSE (Tumbleweed) Grub screens, but in both cases the actual installer fills the whole laptop screen.
Ah yes, there's a similar problem reported in bug 23904. I suggest you attach your picture with a "me too" comment there. I'll close this as the main bug seems to be fixed.
