I’ve installed Leap 15.0 on a Thinkpad T430 in an unorthodox way, identified below as “the second T430”; see https://forums.opensuse.org/showthread.php/534118-Thinkpad-T430-BIOS-update-without-installed-Windows. for installation problems. Installation was faultless on the other T430. (Thank Thinkpad designers for decades for making TP harddisks so accessible.)
Mounting the HD in the second T430, almost everything works except the task bar at the bottom of the screen. Links to open screens have accurate text but thick black bars are overwritten that obscure the text . Applications with task bar links, either defaults or ones that have been added are not correctly rendered. The mouse pointer rolling over links does produce popup mini screens showing the current dominant frame or title frames for task bar applications. A possible related problem is that the current window (e.g., this one) tends to scroll gratuitously although the cursor remains in place and accepts additional key strokes.
As noted in the other post this machine is running BIOS G1ETB2WsW (2.72), the latest version that is downloadable. v2.73 is shown as current, though there is no link to download it on:

It is possible that this problem results from having installed Leap 15.0 with the current HD in the other T430 which is running BIOS G1ETB1WW (2.71), but that was the only way to get Leap 15.0 installed on the current second T430. This install problem on the second T430 occurred in the same way from a downloaded copy and from the DVD copy of Leap 15.0 from OSDisc.com.
I’ve considered that the BIOS on the present machine might be corrupted and needs to be refreshed. The instruction on https://en.opensuse.org/SDB:Live_USB_stick#Install_ImageWriter_for_openSUSE, warns of not creating a bootable stick, other than the procedures shown on that page. Clicking the link to install imagewriter created a page with this error msg:
Error connecting to http://api.infra.opensuse.org//published/openSUSE:15.0/standard/imagewriter?view=ymp: Response was: #<Net::HTTPNotFound:0x000000410cb458> <status code="not_found"> <summary>Couldn't find Project</summary> </status>
Searching for imagewriter found and installed it. Will try using it to create a bootable stick.
This looks like it might be a video driver problem. A search “video driver” from the second T430 produced a page with this information:
xorg-x11-driver-video
**Compatibility metapackage for X.Org video drivers**
This package is a compatibility metapackage. It used to contain the X.Org video drivers.Version 7.6_1
Size 49.6 KB
openSUSE Leap 15.0
Maybe the search script is smart enough to identify the video chipset, but I am hesitant to install this for fear of making matters worse – like a blank screen.
