Internet browser not working

Hello,

Any advise please regarding an internet browser?

I tried Firefox, vivaldi, midori, chromium without success.

Thank you.

Re: Internet browser not working

Are there any specific error messages? What's the output if you start them from a terminal?

Re: Internet browser not working

Given you have an 'AMD Athlon(tm) XP 2000+' I think vivaldi and chromium are no option (both need SSE2).
chromium might be compilable without SSE2 support, given we are using the system ffmpeg, but I didn't test this yet.
I'm a little bit puzzled, why Firefox doesn't work, but I can say that 512 MB for instance are not enough even for
seamonkey. How much memory do you have?

Re: Internet browser not working

That's actually plenty. So, most browser now also use optimizations.. *sigh*.

Can you post a complete 'cat /proc/cpuinfo', especially the flags section of supported features?

Re: Internet browser not working

Ok. You have cmov, mmx and sse. So actually, when we aim at a PIII, then this should be ok.
So the problems must stem from SSE2, I would say..

Re: Internet browser not working

Ok. Just tried on a real Alix1.e, there I can reproduce a segfault:

No, the disassembly doesn't make sense to me (yet, this looks like a completly broken stack).

Unfortunatelly on libvirt/qemu, even when emulating a Pentium III, seamonkey runs without any problems there
(experienced before with iPXE running in Qemu under i486, but not on a real i486).

The flags on the emulation are:

flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 mmx fxsr sse cpuid x2apic hypervisor cpuid_fault
