Uninstall broken Leap from my Toshiba Kepler hybrid(Optimus) laptop

It won’t boot past a black screen with a non KDE movable cursor.

The bumblebee SDB makes it seem very bleak as to getting it working.

I have another thread in Hardware section that points out that I may never get Leap working on that laptop.
plenty of images for various things tried per help instructions from Deano_ferrari

**How do I uninstall and not mess up the windows boot loader?
**
I do not have a Windows 10 install media!

Maybe I will trade my machine for my wife’s MBR Toshiba (if she is willing — HA) with Intel HD only onboard graphics.

Try this, just in case:
Boot to runlevel3
(when the Grub menu shows, hit “e” key to edit the commandline)
Scroll down to the line that begins linux or linux-efi (or something like that), hit the END key to get to the end of the command line (it wraps), add a space, then add “3” (without the quotes). Press F10 to continue.

You will get to a command line interface.

Once there, log in as root.

launch the ncurses version of Yast.

Now, select the Xfce Desktop in Software and install that.

(Probably don’t need to do this, but I suggest rebooting

reboot now

back into runlevel3, log in again as root.
Then:

update-alternatives --config default-xsession.desktop

Choose the corresponding number for the Xfce Desktop.
Then:

update-alternatives --config default-displaymanager

Choose the corresponding number for the LightDM display manager.

Reboot and see what happens.

This is kind of a U.S. “football”-like Hail-Mary Pass, I do not know if it will help out here, but at this point it sure cannot hurt.

Ctrl+alt+F1 gets me to a terminal mode. I think level 3 would do the same, not sure though.
I have been in ncurses yast from there.
I will try your suggestions, but my question still stands, how do I remove Leap and not mess up Windows boot?
(not having a Windows install media, reformat, install Win 7, and upgrade(maybe?).

it seems to me the devs know/knew these situations would raise there awful heads, and gives us a ‘backout’.

Can you boot to Windows?? if so why “remove” Linux?? If you want to reclaim space just format Linux partitions to a Windows format. Can be done from Windows. If EFI boot ing you can remove the openSUSE foled and it won’t boot again ever. If MBR boot just move the boot flag to the Windows boot. If EFI then you may need to reset the UEFI boot menu to first boot Windows.

Yes I can boot from Grub2 into Windows. It is not a painful thing. It is UEFI.
ANother possible problem, there are two EFI boot partitions, probably my mistake when installing and partitioning.
There is the 100MB Windows EFI partition, and another 500MB EFI partition added by the installer.

What is ‘openSUSE foled’? (remember I am a linux dummy)

I don’t need the space, and would be glad to wait until a kernel fix comes out(if ever).

Where, How? That is not a BIOS option.

Ok be sure you can select and boot Windows in the UEFI boot menu ie not through grub.

When it boots it starts grub. There is an option to boot Win10. If I select that and it takes me to what I consider the ‘normal’ Windows boot manager where the only option is Windows 10.
If that is the UEFI boot menu, then I have to go through grub to get to it.
Sorry to be such a dummy.

No you press a hot key at boot sometimes F12 but is different on different machines. This brings you to the UEFI boot menu. where you can chose which OS or device to boot. This is not the grub menu. currently on your machine the default boot is Linux which starts grub. You can at that point choose other OS but that is a Linux program not the UEFI/BIOS. In the UEFI you can set which OS defaults and yes if you choose Windows you no longer have any choice. Linux /grub gives you a choice.

Hail Mary it is!
Two shutdown and boots, and it works with Xfce.(I don’t like Xfce, never did on UNIX nor Suse paid when I had it)
Why does it boot with Xfce and not KDE?
But it works, and I have to figure out how to get my things over to the menu if I am going to use it.
I need to try it with WiFi before I really commit.

I am going to ask this again. I read that there is a kernal update to fix the proble I am having with that black screen non boot into X.
Is there such a thing in the works?

You might give KDE another try, but this time with XDM or LightDM as Display Manager. Try both.

You never know, but I have found that sometimes switching away from SDDM to one of those two works on some machines.

As for me, I now prefer XFCE.

F12 is the ‘hot key’ on my Toshiba S70-A and the options are:
USB
Optical Drive
HDD/SDD
LAN
<Enter Setup>
If I select the HDD/SDD option it does give me the Select a device to boot menu.
> openduse-secureboot
> Windows Boot Manager
> EFI HDD Device (HGST 'harddrive number)

**Another lesson learned! **

Toshiba’s are POC’s IMO, and I am really sorry I bought it!

Anyway Gerry’s suggestion works, but it is Xfce and I guess I will live with it for a while as long as the WiFi works without some password manager getting in my face.

Heh-heh. I use Network Manager, never see such a thing, myself. Auto-connects to my own Router when I turn WiFi on, but most of the time I am connected through ethernet cable with WiFi disabled.

I also have a couple other protected WiFi networks saved, so can simply disconnect from mine and click on one of those to connect. I do that to do maintenance and systems updates for a couple of my neighbours, who I have moved over to openSUSE.

BTW: I have a couple of Toshiba laptops I acquired along the way – drop-offs or castaways – running openSUSE Leap 15.0, and running it very smoothly. Older machines, of course, both Intel, think Core2-Duo or something like that.

They are both good, hardworking machines.

This machine (the one I am using to post this message) is an Asus laptop.

… AND I AM PLEASED THAT YOU ARE NOW UP AND RUNNING!

Hope you don’t mind me shouting, like that, but I sometimes get a bit over-excited.rotfl!

I think you would have to ask that upstream at KDE. Perhaps suggest to them that they ask the Xfce people how it is done?:stuck_out_tongue:

No I don’t mind, but Xfce is just a black sheet and I can’t figure out how to add icons to the desktop, or even if it is possible.
And do I have to use the lightDM?

But I have A Leap on my laptop, Now to gt WiFI working without kwallet slapping me around.

Where should I put a bug report about KDE not starting when Xfce does.

I’m wondering if switching the display manager was sufficient ie maybe sddm is the main issue here. It might still be possible to use KDE (no desktop effects) but with lightdm perhaps? You can set the required display manager with update-alternatives of course.

KDE did not show up in the alternatives. Actually nothing showed up, just came back with the user prompt.
But sddm did show in in the display manager alternatives.

And I may have patted me on the back too soon, I just ran across a graphic problem that pretty much made the screen unusable with open windows.
Getting tired, tomorrow another day.

Yes, KDE is not a display manager. It is a desktop environment. You should be able to choose which desktop session runs at the login screen. I know you haven’t installed Gnome, but the gdm display manager is another option. The desktop environments are independent of these.

Sorry for the confusion!

update-alternatives --config default-xsession.desktop 

There is only one alternative in link group default-xsession.desktop (providing /usr/share/xsessions/default.desktop): /usr/share/xsessions/icewm-session.desktop

update-alternatives --config default-displaymanager
