debian 11 screen flashing (can login remote) (5 stars)

Hello - this is a new debian install is flashing; able to login remote and did get all updates What in the world is going on? 5 seconds, flash, 5 seconds, on, then flash again There is a TOTAL max budget of $15 on this project regardless of the time; selected hourly so there would be less % taken between us ========== There is hope you can give your “best” price; unemployed, and have cancer with bills backing up, $15 possible? Glowing paragraph of feedback 5 stars My funds are low but will pay quick and leave 5 stars. Please give your best possible for your bid ? (something reasonable?) Please note there is hope we can mutually complete this task; we can leave each other nice comments and 5 stars for each? Look at feedback on my profile, feedback I left for many others. Here is the project: SINCERELY WOULD BE NICE TO MEET YOU PLEASE ANY THOUGHTS ? Please note project is due in two hours as this projects deadline, as this is needed if we can get some done - then we can talk about next steps and 5 stars and another job also. If this is a good one and we are "successful"; would need a couple others setup, but will handle one at a time? Can you do this for something reasonable in a couple hours? thoughts ?
