not sure what this question means as "IF" Schwab drops support for linux you'd have to go to a supported OS like windoze or apple. IF you mean could you run tos in a virtual machine then yep but I personally wouldn't do that. You could run wine or whatever the latest is for that but I don't mess with that stuff and no one I know does, it's too much for little. We're ( all 200 of us, retired from the valley) are moving on. TD was EXCELLENT bu the Schwab people are not. Some of the family officers have refused to carry on discussions with them. Not a great sign.
