Description Forgotten User U_vfIZ_agZ 2017-02-28 14:41:32 UTC

User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0
Build Identifier: 

I have both a Dell 1721, and 1720 laptop. Both have external VGA connector. If the second monitor (external is not hooked up/connected and perhaps powered on. At the initial boot selection (boot from hard drive, installation, .... more.. rescue). The Laptop monitor goes blank (actually green haze. Same thing occurs with when rescue is selected. The installation option problem was also identified by me on upgrade to I believe 13.x, but, this problem did not exist on version 11.x and 12.x I rated it as normal level problem, whomever reviewed it upgraded it to critical, so this time instead of normal, I upgraded it to major. The "bug" has come back.  It would probably discourage people from using this OS and linux OS all together at least at this early stage.



Reproducible: Always

Steps to Reproduce:
1.Put in iso disk/stick, turn on computer
2. Make either a selection of a) installation or b) (more) rescue. 
3.
Actual Results:  
Blank screen (acutally green haze) after selecting installation or rescue. 

Expected Results:  
Information during installation, and rescue should always be on the laptop screen, the external monitor/screen be nice; but, not critical IMHO.

Steffen - rescue should not start any X so probably problem with framebuffer? Maybe kernel issue? I guess you have better knowledge who to reassign to.

Comment 2 Steffen Winterfeldt 2017-02-28 15:28:28 UTC

I'll need a bit more details.

Rob, do you mean you hit 'enter' and the screen screws up immediately, or
do you see the 'Loading Linux kernel' popup and only _after_ that one
the screen goes blank (that is, when the kernel starts)?

Just Re-created what happened this morning with a Dell Inspiron (Intel CPU) 1720 with Nvidia Graphics Board (8600M 256. Just previous to that I tried to recreate it with the Dell Inspiron 1721 (graphics is a chip  on the motherboard)  could not duplicate this bug on the Insprion 1721 (AMD CPU)  - perhaps this was version 42.1 - and just hooked up a external monitor. 



Dell Inspiron 1720 below. I selected the rescue mode from the choices from the first window. 

Basically, the window with "Starting .... Loading linux Kernal" does complete. Monitor then goes into "text mode" and start scrolling with text.  

Shortly after the display reads  ">>> openSuSE Leap 42.2 installation program v5.0.87 (c) 1996-2016 SUSE LLC <<< Starting udev ..."

The screen then goes "blank" shortly thereafter.

Thanks! That clears things up.

This is the moment when KMS takes over. As a workaround you could
pass 'nomodeset' as boot option.

Assigning to kernel team.

Closing due to lack of response.
