Mageia 7 full install graphical issues?

Maybe it's just me, since I'm not seeing anyone else posting about it.

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.

This same issue is NOT present on the Live DVD (XFCE or KDE, have not tried Gnome); but it is also present on the Mageia 6 full ISO.



I'm not sure how to correct this. Is the Full ISO trying to load some video driver that is incompatible with my system (intel graphics) where the Live DVD is not? I remember having this error before, way back in the day, but I can't remember how I solved it. I imagine adding something to the boot options might help, but I'm not really sure what.

Could you add some context information what hardware you're using ? graphics card, mainboard or laptop model / make etc.

Beta 1?

You could try with xdriver=vesa as boot option.

I also question why you are using beta 1, not the final release. But apart from that, at the GRUB boot menu, press 'e' to edit the boot command line and try:
1. Deleting the option vga=791
2. Adding the option nomodeset
3. Both the above
4. Change $linux to linux and $initrd to initrd (you must do both together)

@doktor5000, the xdriver= option is only recognised and acted upon by service_harddrake, so won't have any effect on the installer. And IIRC, the installer only ever uses the framebuffer device (the intention is to maximise the chances of it working on all hardware, although clearly failing here :-( ).

Well, that's not strictly true - I think it would affect the default driver selected for the installed system, but not for the installer itself.
