Hi redsonja and welcome!
There are tips and tricks for reducing gas caused by consuming dried cooked beans. Rather than explain it all myself, I will refer you to this article as a resource since it is quite extensive:

And this quick tip:

Also, you can add a piece of kombu or other sea vegetable (usually found in Asian groceries or Asian section of natural food stores) to your pot of cooking beans to help draw out the sugars that cause flatulance. Rinse your beans well after cooking before storing or consuming.
If you eat canned beans, drain and rinse them first before using to reduce the salt from the liquid (canned foods are much higher in salt/sodium than bulk items).
If you aren't used to eating a lot of vegetables and fruits, try chopping them well before chewing them, and/or cook them first. Some vegetables tend to cause more flatulence than others, such as broccoli and cruciferous veggies, so going light on those at first might help. Root vegetables (carrots, jicama, turnips, potatoes/sweet potatoes) tend to be less likely to cause gas.
As mentioned, fruit is often better eaten by itself. I can handle eating it with oatmeal or toast or even nuts, but I never eat fruit with beans, tomatoes, and other types of foods. Certain combos just seem to make the gas worse.
Increase fiber slowly. Allow for more tofu based dishes, nut/seed butters or peanut butter, and pastas while you become more accustomed to more fiber. Then focus more on whole grains, more vegetables and beans and so on as your body gets used to them.
I think that flatulence from vegetables and beans is far less raunchy than that from dead flesh and dairy! My gas tends to be "clean". I am guilty of passing gas in public a few times and no one even bats an eye or lets on that they smell anything lol.
Give yourself plenty of time to adjust! Your gut flora will change over time, but it doesn't happen overnight. I have been vegan almost six years, but I actually started introducing more beans and far less meat in 2007 due to digestive issues with meat and abdominal issues after three surgeries for endometriosis. I vaguely remember suffering with gas and bloating at first, but over time my body became accustomed to it. I can eat a cup or two of beans now in a sitting no problem!
I have so many different breakfasts I start my day with! Sometimes it is beans on toast, sometimes oatmeal and fresh berries, sometimes smoothies (with leafy greens, frozen banana, fresh fruit, chia seeds, plant milk); sometimes it is sauteed tempeh, pineapple, and bok choy with lemon juice and ginger. Sometimes it is wild rice and blueberries (I cook a huge batch of wild rice and freeze it since it takes time to cook). Sometimes it is crockpot millet and apples, or steel cut oats, or canned pumpkin, banana, and blackstrap molasses all mashed together in a bowl. I could go on and on!
