Mageia 4 Live DVD KDE 64-bit graphics not working

[merlin]

I have a Dell Latitude E6430 laptop that I use for work. It has 2 graphics outputs, namely:

LCD: Using Intel 810 or later, driver: intel
HDMI: Using nVidia GeForce 400 and later, driver: nvidia

I run Mageia 3 natively on the laptop.

On Mageia 3 this is a nightmare because XFdrake (I assume) fails to create a working xorg.conf file. I have to manually create separate xorg.conf files; 1 file for LCD and 1 file for HDMI (external monitor). I do find that the running xorg.conf file becomes re-written with bad settings especially on a bad shutdown so I have to manually copy back my working xorg.conf file to fix it.

I was hoping that Mageia 4 would be more successful in getting the graphics to work on my laptop but sadly Mageia 4 Live KDE DVD 64-bit fails to get any graphics working. The boot sequence shows the Mageia screen with the "bubbles". I think it gets to showing 3 bubbles on the LCD before the screen goes blank for a little while, probably trying to start the X server. Eventually, the LCD screen shows some white dots and dashs that I guess are pixels of white text. I suspect the pixel frequency is wrong so the text appears malformed eg. out of sync. I can press the return key and I get more lines of dots and dashs so the system is alive. The external monitor via HDMI shows a blank screen.

I can boot using safe mode and I get a non-graphical login prompt on the LCD screen. Manually, trying to run startx fails.

I think that the xorg.conf file is incorrect for my laptop eg. malformed. I guess that I could try manually copying across my manually created Mageia 3 xorg.conf files to see whether that works.

Has anybody else had similar issues with laptops that have 2 graphics outputs ?

I have a similar problem running on a Dell Latitude D630 64 bit. During the install or live boot, the X server crashes trying to load the Intel driver... Worked fine in previous versions 2 and 3.

Doesn't sound like the same problem. For your issue please have a look at https://wiki.mageia.org/en/Mageia_2_Err ... rd_drivers

Thanks for Mageia 2 link, it says:

Live CDs
Depending on your card you may add in the grub (f6):
xdriver=nouveau
xdriver=nvidia
xdriver=intel (if you have a system with both intel and nvidia gpu)

When I get time, I will try those settings to see what happens.

Yes not quite the same.

I get similar output to bug: https://bugs.mageia.org/show_bug.cgi?id=6077

Seems to be quite an old bug. I can probably install with the Vesa driver and hope that the issue goes away after install. Funny thing is that this bug is a few years old (2012) but my Dell laptops worked without issues and all the previous Mageia versions except Mageia 4. Was hoping to use the latest version for training, but having to use the Vesa driver during install will look bad! I hope there will be an easy fix/patch.

Please open a separate thread for that. As a general hint and golden rule: Please only one problem per thread
