Thank you for contacting Intel Communities.
Regarding the support for Tablets/Graphics/Drivers from OEMs.
The OEM is the one that designed and integrated the device, therefore, the support would be provided by them.
I was able to find the Customer support email that you can use to get the correct troubleshooting for this situation.
Their website: Linx Tablets
You are very welcome.
Do not hesitate to contact the Intel Communities if any additional or new inquiries come.
